AB  - N-doped TiO2/carbon composites (TiO2/CN) with different nitrogen content, were obtained starting from titanium isopropoxide and glucose, and by varying the amount of melamine, added to starting reaction mixture. For comparison, an undoped sample (TiO2/C) was also prepared. Structural and surface characteristics were determined through scanning electron microscopy, thermogravimetric analysis, elemental analysis, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction and nitrogen adsorption–desorption isotherms. The photocatalytic activity of TiO2/CN composites was examined via photocatalytic degradation of methylene blue and multiclass pharmaceuticals from water solution. It was found that N doping of TiO2/carbon composites induced changes in structural and surface characteristics of TiO2/CN composites, improving their adsorption, but decreasing photocatalytic efficiency. Nevertheless, TiO2/CN0.05 composite obtained by the hydrothermal synthesis in the presence of glucose and 0.05 g melamine showed the highest efficiency for removing selected pharmaceuticals and methylene blue from aqueous solutions through the combined processes of adsorption in the dark, and photocatalytic degradation under UV and visible irradiation.

AB  - Nanoemulsion technique based on Ouzo effect was applied for the fast and simple synthesis of Ag3PO4 at room temperature. X-ray powder diffraction analysis and Raman spectroscopy reviled that synthesized powder was single-phase. Using scanning electron microscopy analysis, it was found that the synthesized Ag3PO4 particles were near-spherical shape with an average diameter of 100 nm. The high value for the specific surface area of obtained powder was measured by Brunauer–Emmet–Teller method. Finally, the Ag3PO4 product was used as a photocatalyst for the photodegradation of crystal violet dye in an aqueous solution. Nanoemulsion strategy procedure provides a simple pathway to obtain a highly efficient single-phase Ag3PO4 photocatalyst.

AB  - The influence of the structure type on the boron nitride (BN) properties such as excellent thermal and chemical stability and super hardness is well known. The effect of aluminum addition on four different structure types of boron nitride (wurtzite, h-BN, sphalerite, and rock salt) and its electronic properties have been investigated in our study. Here we present an ab initio study of the B1-xAlxN solid solutions for (x ​= ​0; 0.125; 0.25; 0.375 and 0.5), and corresponding structure-property relationship. Novel structures have been discovered in new Al-rich boron nitride compounds and some of them indicate AlN-BN layer separation. Electronic properties have been studied in great detail using hybrid B3LYP approximation. Present results suggest great diversity of the electronic properties generated by adding aluminum to boron nitride and that by using these predicted modifications in various investigated AlN-BN compounds, one could obtain fine-tuning of the band gap in boron nitride electroceramics.

AB  - In this study carbon cryogel, cryogel doped with nitrogen, and both nitrogen and sulfur co-doped carbon cryogels (nominal concentration of nitrogen was in the range 2–10 wt%) were synthesized and used as an adsorbent for the removal of carbamazepine, naproxen, diazepam and diclofenac from water. A batch adsorption kinetics study was performed by determination of contact time influence, the effect of pH, and adsorption isotherms. Structural and morphological analysis showed that there are no changes in turbostratic carbon structure induced by doping/co-doping, but noticeable morphology changes were observed. The presence of both nitrogen and nitrogen/sulfur were confirmed and results showed low content on the surface, especially for sulfur. Obtained high values of the specific surface area for co-doped samples (up to 1530 m2/g) can be caused by sulfur atoms burning or leaving the material during carbonization. The results of the adsorption kinetics study showed that the adsorption of all pharmaceuticals on all tested samples followed the pseudo-second-order kinetic model. The maximum adsorption capacity obtained from the Langmuir isotherm model is higher for doped (91.28–168.92 mg/g) and co-doped (152.97–488.06 mg/g) samples than for pristine sample (59.75–266.28 mg/g). Calculated adsorption energy values from the Dubinin-Radushkevich model indicate that the possible mechanism was physisorption. Desorption tests that were carried out showed satisfactory reusability for all samples. The favorable adsorption characteristics for the co-doped sample with a higher nominal concentration of nitrogen and sulfur qualifies as a potentially good adsorbent for the removal of pharmaceuticals from water.

AB  - Carbonaceous solid-phase extraction (SPE) sorbent, efficient in isolation and enrichment of multiclass pesticides and pharmaceuticals from water, was synthesized starting from cheap waste beech sawdust and using KOH as the activated agent. The first step in carbon material preparation was hydrothermal carbonization of the waste beech sawdust. Following hydrothermal treatment, the obtained material was activated, using different amounts of KOH. It was found that applied activation leads to changes in material structure, an increase in specific surface area, and a decrease in the number of surface oxygen groups compared to carbonized sample. SPE procedure of multiclass pesticides and pharmaceuticals from water using activated carbonized beech sawdust (AcSD) was optimized by selecting the appropriate elution solvents, the sample pH, and the sample volume to obtain the highest enrichment efficiency. The optimized SPE procedure was applied for water analysis using different AcSD samples as a sorbent for analyte preconcentration. Activated carbon sorbent, obtained with the highest amount of KOH, showed the highest recoveries regarding the most analytes, which were comparable with the recoveries obtained by commercial cartridges. © 2022 Serbian Chemical Society.

AB  - In this study, the influence of boron doping on structural and surface properties of carbon material synthesized by a hydrothermal method was investigated, and the obtained results were compared with the previously published influence that boron has on characteristics of carbonized boron-doped hydrothermal carbons (CHTCB). Hydrothermal carbons doped with boron (HTCB) were obtained by the hydrothermal synthesis of glucose solutions with different nominal concentrations of boric acid. It was found that glucose based hydrothermal carbon does not have developed porosity, and the presence of boron in their structure has insignificant influence on it. On the contrary, additional carbonization increases the specific surface area of the undoped sample, while an increase in boron content drastically decreases the specific surface area. Boron doping leads to a decrease in the amount of surface oxygen groups, for both, hydrothermally synthesized and additionally carbonized materials. Raman analysis showed that the boron content does not affect a structural arrangement of the HTCB samples, and Raman structural parameters show a higher degree of disorder, compared to the CHTCB samples. Comparison of structural and surface characteristics of hydrothermal carbons and carbonized materials contributes to the study of the so far, insufficiently clarified influence that boron incorporation has on the material characteristics. © 2022 Serbian Chemical Society.

AB  - Carbon cryogel (CC) was impregnated with magnetite to produce a multifunctional magnetic adsorbent capable of removing phenoles and phosphates from water. Adsorbents were prepared via co-precipitation of Fe2+ and Fe3+ ions in aqueous solution in the presence of CC. Non-treated or acid-activated CC was used. The CC: Fe3O4 ratios of 1:1 and 3:1 were applied. The addition of HCl in the synthesis process was also investigated. XRD confirmed the formation of nanocrystalline magnetite. BET analysis showed that the pre-treatment diminished the CC porous structure, reducing also specific surface area (Sp). Formation of magnetite decreases Sp and total volume of micro and meso pores, but their distribution remained unchanged. FTIR spectra revealed that magnetite was attached to the surface of the acid activated CC via C═O bond. DTA-TGA and SEM indicated that acid treatment and presence of HCl were beneficial for homogeneous nucleation and distribution of magnetite, increasing adsorption properties of composite. Batch adsorption proved that the maximum adsorption capacity for phenoles was accomplished with 3:1 ratio with non-treated CC. Samples synthesized with pre- treated CC, under 1:1 ratio, gave the best results for phosphate removal. The CC/magnetite composite was found as promising adsorbent for the simultaneous removal of both polutants.

abstract = "Carbon cryogel (CC) was impregnated with magnetite to produce a multifunctional magnetic adsorbent capable of removing phenoles and phosphates from water. Adsorbents were prepared via co-precipitation of Fe2+ and Fe3+ ions in aqueous solution in the presence of CC. Non-treated or acid-activated CC was used. The CC: Fe3O4 ratios of 1:1 and 3:1 were applied. The addition of HCl in the synthesis process was also investigated. XRD confirmed the formation of nanocrystalline magnetite. BET analysis showed that the pre-treatment diminished the CC porous structure, reducing also specific surface area (Sp). Formation of magnetite decreases Sp and total volume of micro and meso pores, but their distribution remained unchanged. FTIR spectra revealed that magnetite was attached to the surface of the acid activated CC via C═O bond. DTA-TGA and SEM indicated that acid treatment and presence of HCl were beneficial for homogeneous nucleation and distribution of magnetite, increasing adsorption properties of composite. Batch adsorption proved that the maximum adsorption capacity for phenoles was accomplished with 3:1 ratio with non-treated CC. Samples synthesized with pre- treated CC, under 1:1 ratio, gave the best results for phosphate removal. The CC/magnetite composite was found as promising adsorbent for the simultaneous removal of both polutants.",

AB  - Resorcinol–formaldehyde (RF) cryogels were synthesized by sol–gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels in an inert atmosphere to 950 °C. Nitrogen doped CCs (CCN) were synthesized by introducing melamine into RF precursor mixture solution to obtain nitrogen concentration 2, 6 and 10 wt.%. Material was characterized by elemental analysis, nitrogen adsorption– desorption measurements, scanning electron microscopy (SEM), Raman spectroscopy, FT-IR Spectroscopy. Cyclic voltammetry (CV) was used to investigate capacitive and electrocatalytic properties. Conductivity measurement was also performed. Elemental analysis results confirmed presence of nitrogen in CCN samples in the range from 0.45 to 1.15 wt.%. Raman spectroscopy of the samples showed increase of D and G peak integrated intensity ratio (ID/IG) with nitrogen doping suggesting that the structural disorder as well as edge plane density increase, but according to similar ID/IG values for CCN samples, their share is not directly related to the amount of incorporated N. Characterization by nitrogen adsorption showed that overall specific surface and maximum mesopores are achieved in CCN sample with medium nitrogen concentration. Results of cyclic voltammetry experiments demonstrated maximum capacitance for CCN sample with smallest N wt.% indicating that narrow pore size distribution and high specific surface area are dominant factors to achieve good capacitive behavior. The relatively low doping level of nitrogen reached in CCN samples may be the reason for the incomplete reduction of oxygen to hydroxide and furthermore it turned out that presence of N in the structure of CC had a negligible effect on the otherwise relatively high conductivity of CC. © 2019 Elsevier B.V.

AB  - This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the influence of surface properties on hormone adsorption, chemical modification of ACCs with HNO3, HCl, or KOH was employed. Applied treatments increased the specific surface area and changed the content of oxygen functional groups. Increased content of acidic surface oxygen functionalities enhanced adsorption efficiency up to 30 % and had a more dominant influence on adsorption capacity than specific surface area. Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol followed pseudo-second-order kinetic model, while the equilibrium adsorption data fitted well with the Freundlich isotherm model. Calculated mean sorption energy values of 1.4475, 1.3387, and 1.0541 kJ/mol, for E1, E2, and EE2 respectively, indicated that removal of selected hormones was dominated by physisorption mechanism. Obtained Langmuir adsorption capacities, 12.34, 12.66, and 11.11 mg/g for estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol, respectively, as well as convenience of manipulation, recommend activated carbon cloth modified with HNO3 as an efficient adsorbent for removing estrogen hormones from the water.

AB  - The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3–15 wt% Fe2O3 were synthesized by a combination of sol-gel and combustion methods. The excess of water and urea were introduced in reaction solutions to enhance the copolymerization of aluminum and silicon species. The results of structural characterization revealed that the synthesized mullite powders were amorphous of a hybrid type. The specific surface area of the undoped mullite powder was 262 m2 g-1 with a maximum pore radius (dp) of 2 nm classifying it into mesoporous materials. The addition of iron has reduced the specific surface area, while the pore size value remained the same except for the sample with 3 wt% Fe2O3 (SBET = 278 m2 g-1; dp = 3 nm). The presence of iron caused lowering the temperature of liquid phase formation, while present urea combusted providing the increase of the temperature locally that caused the sintering and formation of agglomerates of smaller particles. However, the results of the particle size analysis are not straightforward. The values of mean volume diameter (D[3,4]) indicated that the particle size increased to 6 wt% Fe2O3 (123.6 μm), and then decreased and for the sample with 12 wt% Fe2O3, it was equal to 96.6 μm. Thus, the added iron contributed to the more uniform particle size distribution. The SEM analysis has also shown the coarse powder particles consisted of the coalesced smaller particles. © 2020 Elsevier Ltd and Techna Group S.r.l.

AB  - Nanofibrous silica with a high surface area was produced from chrysotile by the acid-leaching method. Natural mineral chrysotile asbestos from Stragari, Korlace in Serbia was used as the starting material. The fibers were modified by chemical treatment with 1 M HCl and the mineral dissolution was monitored by transmission electron microscopy, X-ray powder diffraction, inductively coupled plasma spectrometry and low-temperature nitrogen adsorption techniques to highlight the effects of the leaching process. The results showed that the applied concentration of acid solution and processing time of 4 h were sufficient to effectively remove the magnesium hydroxide layer and transform the crystal structure of the hazardous starting chrysotile to porous SiO2 nanofibers. With prolonged acid leaching, the specific surface area, S (BET), calculated by BET equation, was increased from 147 up to 435 m(2) g(- 1), with micropores representing a significant part of the specific surface.

AB  - Monoclinic scheelite-type BiVO4 is currently considered as one of the most promising non-titania photocatalysts, wheras tetragonal zircon-type BiVO4 is still poorly understood. Herein, a new and simple synthetic approach was applied and nanostructured single-phase zircon-type BiVO4 was successfully prepared by a controllable ethylene-glycol colloidal route. In addition, nanostructured monoclinic scheelite-type BiVO4 powders were also fabricated through annealing of the as-prepared samples. A comparative study of the two BiVO4 polymorphs was conducted and it turned out that the novel synthetic approach had a significant impact on porosity and photocatalytic performance of zircon-structured BiVO4. All the prepared materials, as-prepared and annealed, were mesoporous, while measured values of specific surface area of some zircon-structured samples (∼34 m2/g) were ∼7 times higher than those reported thus far for this phase. Interestingly, for the first time, zircon-type BiVO4, previously considered to be a poor photocatalyst, exhibited a better overall performance in degradation of methyl orange compared to monoclinic scheelite-type BiVO4. Hence, it could be expected that the here-presented synthesis and observations will both arouse interest in scarcely studied tetragonal zircon-type BiVO4 and facilitate as well as speed up further research of its properties. © 2018 Elsevier Ltd and Techna Group S.r.l.

AB  - Zagađenje vodenih tokova teškim metalima je jedan od najakutnijih ekoloških
problema današnjice. S obzirom na to da teški metali nisu biorazgradivi, oni se akumuliraju
u životnoj sredini i na taj način ulaze u lanac ishrane ljudi i životinja, pa kao veoma toksične
materije, mogu izazivati niz opasnih i često neizlečivih bolesti. Iz tog razloga, istraživači
godinama u nazad razvijaju nove i usavršavaju postojeće tehnike za prečišćavanje otpadnih
voda od ovih zagađujućih materija [1]. Za prečišćavanje vode zagađene teškim metalima
mogu se koristiti različite metode: hemijska precipitacija, elektrohemijski tretmani, filtracija,
reverzna osmoza, jonska izmena, membranski procesi, adsorpcija. Jedna od najčešće
korišćenih je adsorpcija, koja zbog mogućnosti regenerisanja adsorbenta, odgovarajućim
desorpcionim procesom, predstavlja veoma efektivnu i ekonomičnu metodu. Zahvaljujući
razvijenoj specifičnoj površini i poroznosti, kao i prisustvu funkcionalnih grupa na površini,
različiti ugljenični materijali pokazuju visoku efikasnost u uklanjanju teških metala iz
vode. Karbon kriogel (CC) predstavlja ugljenični materijal razvijene mezoporoznosti čije
se adsorpcione karakteristike mogu poboljšati optimizacijom i kontrolisanjem parametara
dobijanja. U ovom radu je ispitana mogućnost uklanjanja jona teških metala (Cd2+, Ni2+ i
Zn2+) iz vode, korišćenjem karbon kriogela i hemijski modifikovanog karbon kriogela.
Prvi korak u sintezi karbon kriogela je polikondenzacija rezorcinola i formaldehida,
u prisustvu natrijum-karbonata kao katalizatora. Organski kriogel pripremljen je solgel tehnologijom uz naknadno sušenje postupkom zamrzavanja, dok je karbonizacija
organskog kriogela vršena u inertnoj atmosferi argona na temperaturi od 800 o
C [2]. U
cilju poboljšanja adsorpcionih karakteristika karbon kriogela, izvršeno je hemijsko
modifikovanje korišćenjem 5 M HNO3
. Karakterizacija materijala izvršena je merenjem
specifične površine BET metodom, određivanjem tačke nultog naelektrisanja metodom
masene titracije, kao i određivanjem vrsta funkcionalnih grupa prisutnih na površini
materijala, metodom infracrvene spektroskopije sa Furijeovom transformacijom (FTIR).
Ispitan je uticaj pH vrednosti rastvora, početne koncentracije jona metala u rastvoru, kao i
vremena kontakta na adsorpciju teških metala uzorcima karbon kriogela.Primenjenom hemijskom modifikacijom karbon kriogela ne dolazi do bitnijih
promena u specifičnoj površini i poroznosti materijala. S druge strane, ovim postupkom
dolazi do izmene površinske hemije materijala, uvođenjem novih, i povećanjem broja
postojećih kiselih površinskih grupa, što je pokazano FTIR analizom i smanjenjem
vrednosti tačke nultog naelektrisanja sa pHPZC = 9,3 na pHPZC = 3,1. Adsorpcija jona teških
metala na modifikovanom i nemodifikovanom karbon kriogelu vršena je na pH = 6, jer pri
ovoj pH vrednosti materijali pokazuju najveći adsorpcioni kapacitet, a ujedno je izborom
ove pH izbegnuta precipitacija hidroksida metala. Izmene u hemiji površine dovode i do
izmena adsorpcionih karakteristika karbon kriogela. Kako površinske grupe predstavljaju
aktivna mesta za adsorpciju jona teških metala, povećanje količine površinskih grupa kod
modifikovanog karbon kriogela dovodi do višestrukog povećanja adsorpcionog kapaciteta.

AB  - The incorporation of trace amounts (<0.2%) of Co and Ni noticeably enhanced the catalytic activity of nitrogen-free ordered mesoporous carbon (OMC) towards oxygen reduction reaction (ORR). (Co,Ni)-doped OMCs were characterized by N2-adsorption measurements, X-ray powder diffraction, field emission scanning electron microscopy and Raman spectroscopy methods, and their ORR activity was estimated by voltammetry on rotating disk electrode in acidic and alkaline media. (Co,Ni)-doped OMCs show modest activities in acidic media, while the catalytic activity in alkaline media is rather high. The measured activities are compared to the Pt-based and Pt-free ORR catalysts reported in the literature. The number of electrons consumed per O2in metal-doped OMCs was found to vary between 2 and 4, which is advantageous in comparison to metal-free OMC. Also, the mass activities of metal-doped OMCs were found to be up to 2.5 times higher compared to that of metal-free OMC. We suggest that the ORR activity is governed by a balance between (i) textural properties, which determine the electrochemically accessible surface of the catalyst and which are influenced by the addition of a metal precursor, and (ii) novel active sites formed upon the introduction of metals into the carbon structure. In particular, our Density Functional Theory calculations suggest that Co and Ni atoms embedded into the single vacancies of graphene can activate the O2molecule and contribute to the decomposition of peroxide.

AB  - Mesoporous silica SBA-15 materials of high specific surface area (similar to 700 m(2) g(-1)) were synthesized by using block copolymer Pluronic P123 as template and tetraethoxysilane as silica source. The obtained materials were characterized by XRD, nitrogen adsorption desorption measurements, SEM, EDS and AFM analysis. It was found that small modifications of synthesis conditions influenced the morphological features of the synthesized SBA-15 samples. The SEM analysis had shown that the SBA-15 synthesized at lower temperature and longer time of reaction (80 degrees C, 48 h) provided elongated rod-shaped grains about 1 mu m long. The other sample synthesized at higher temperature and shorter time of reaction (100 degrees C, 24 h) had rounded grains and grains of regular spherical shape with diameters ranging from 0.5 to 2 mu m. The EDS analysis confirmed that the particles of both synthesized samples were of the SiO2 content. In addition, the AFM analysis had shown different surface morphologies of the materials synthesized under various conditions.

AB  - Synthesis of monetite (CaHPO4) by means of mechanochemical treatment of brushite (CaHPO4∙2H2O) was studied. Start sample (Brushite) was obtained by precipitation method at room temperature. Particle size of brushite was reduced using vibromilling. The powders were analyzed by X-ray powder diffraction (XRPD). Microstructure and morphology was determined by means of scanning electron microscopy (SEM). Brunauer-Emmett-Teller (BET) method was used for examining specific surface area of obtained powders. It was found that five minutes of milling induces brushite-monetite phase transformation. This type of synthesis is cost-effective compared to the other used methods for synthesis of monetite.

AB  - Ultrafine CeO2-delta nanopowder, prepared by a simple and cost-effective self-propagating room temperature synthesis method (SPRT), showed high adsorption capability for removal of different azo dyes. Batch type of adsorption experiments with fixed initial pH value were conducted for the removal of Reactive Orange 16 (RO16), Methyl Orange (MO), and Mordant Blue 9 (MB9). The equilibrium adsorption data were evaluated using Freundlich and Langmuir isotherm models. The Langmuir model slightly better describes isotherm data for RO16 and MO, whereas the Freundlich model was found to best fit the isotherm data for MB9 over the whole concentration range. The maximum adsorption capacities, determined from isotherm data for MO, MB9, and RO16 were 113, 101, and 91 mg g(1) respectively. The adsorption process follows the pseudo-second-order kinetic model indicating the coexistence of chemisorption and physisorption. The mechanism of azo dye adsorption is also discussed.

AB  - In this work, we investigated the properties of carbon resorcinol-formaldehyde (RF) cryogel thin films. RF cryogels were doped by single-wall carbon nanotubes, graphene and graphene quantum dots. The structure of the deposited films was investigated by Raman spectroscopy, and optical, transmission electron and atomic force microscopy. Raman spectroscopy was performed using three excitation laser energies in the visible range. The effect of glass substrate on the Raman features of investigated carbon cryogel thin films was determined as well. The particle size of the carbon-doped RF cryogel thin films was determined by atomic force microscopy.

AB  - Porous CeO2 was obtained by bio-inspired route using egg shell membranes (ESM) as a template. ESM extracted from the fresh chicken eggs were washed with distilled water and immersed in solution of Ce(NO3)(3) x 6 H2O for seven days. Samples were subsequently thermally treated at temperature ranging from 600 to 1200 degrees C in argon and air.To study the crystallization process, samples were heated to temperature ranging from 600 to 1200 degrees C, in air, at different temperatures (600, 800, 1000 and 1200 degrees C). Samples were characterized by nitrogen adsorption measurements, X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD of samples revealed that well crystallized CeO2 is obtained even at temperature as low as 600 degrees C. SEM images confirmed that morphology of obtained CeO2 is a replica of the morphology of the original ESM.

AB  - Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed on a hot plate until a precomposite gel was formed. Pyrolysis of these gels resulted in monoclinic hafnia and cubic hafnium carbide materials, which after subsequent heat treatment completely transformed into hafnium carbide. The obtained materials were analyzed by means of X-ray diffraction and electron microscopy investigations. The results showed that the obtained carbide powder was composed of nearly equiaxed particles of narrow size distribution. Characterization by nitrogen adsorption showed that the precomposite gels and the composite powders were micro and mesoporous materials with high surface areas.

AB  - A novel method for synthesis of carbon cryogel/zeolite composites was obtained. Method considers forming of carbon cryogel from the sol-gel polycondenzation of resorcinol and formaldehyde, followed by freeze drying, and subsequent pyrolysis in presence of different amount of zeolite. Characterization of composite materials by nitrogen adsorption shows that samples are micro- and mesoporous and that specific surface area decrease with increasing the amount of zeolite in samples. XRD method confirms amorphous structure of carbon cryogel and crystalline structure of zeolite, i.e. structure of zeolite has not been destroyed by carbonization process. SEM and EDX analyses reveal homogenous distribution of zeolite through out carbon cryogel and corresponding composition.
