AB  - In search for novel materials to replace noble metal-based electrocatalysts in electrochemical energy conversion and storage devices, special attention is given to a distinct class of materials, MAX phase that combines advantages of ceramic and metallic properties. Herein, Nb4AlC3 MAX phase is prepared by a solid-state mixing reaction and characterized morphologically and structurally by transmission and scanning electron microscopy with energy-dispersive X-ray spectroscopy, nitrogen-sorption, X-ray diffraction analysis, X-ray photoelectron and Raman spectroscopy. Electrochemical performance of Nb4AlC3 in terms of capacitance as well as for oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) is evaluated in different electrolytes. The specific capacitance Cs of 66.4, 55.0, and 46.0 F g−1 at 5 mV s−1 is determined for acidic, neutral and alkaline medium, respectively. Continuous cycling reveals high capacitance retention in three electrolyte media; moreover, increase of capacitance is observed in acidic and neutral media. The electrochemical impedance spectroscopy showed a low charge transfer resistance of 64.76 Ω cm2 that resulted in better performance for HER in acidic medium (Tafel slope of 60 mV dec−1). In alkaline media, the charge storage value in the double layer is 360 mF cm−2 (0.7 V versus reversible hydrogen electrode) and the best ORR performance of the Nb4AlC3 is achieved in this medium (Tafel slope of 126 mV dec−1).

AB  - For the first time, composites of metal-organic framework MOF-5 and conjugated polymer polyaniline (PANI), (MOF-5/PANI), prepared using PANI in its conducting (emeraldine salt, ES) or nonconducting form (emeraldine base, EB) at various MOF-5 and PANI mass ratios, were evaluated as electrode materials for the electrochemical detection of cadmium (Cd2+) and lead (Pb2+) ions in aqueous solutions. Testing of individual components of composites, PANI-ES, PANI-EB, and MOF-5, was also performed for comparison. Materials are characterized by Raman spectroscopy, scanning electron microscopy (SEM) and dynamic light scattering (DLS), and their electrochemical behavior was discussed in terms of their zeta potential, structural, morphology, and textural properties. All examined composites showed high electrocatalytic activity for the oxidation of Cd and Pb to Cd2+ and Pb2+, respectively. The MOF/EB-1 composite (71.0 wt.% MOF-5) gave the highest oxidation currents during both individual and simultaneous detection of two heavy metal ions. Current densities recorded with MOF/EB-1 were also higher than those of its individual components, reflecting the synergistic effect where MOF-5 offers high surface area for two heavy metals adsorption and PANI offers a network for electron transfer during metals’ subsequent oxidation. Limits of detection using MOF/EB-1 electrode for Cd2+ and Pb2+ sensing were found to be as low as 0.077 ppm and 0.033 ppm, respectively. Moreover, the well-defined and intense peaks of Cd oxidation to Cd2+ and somewhat lower peaks of Pb oxidation to Pb2+ were observed at voltammograms obtained for the Danube River as a real sample with no pretreatment, which implies that herein tested MOF-5/PANI electrodes could be used as electrochemical sensors for the detection of heavy metal ions in the real water samples.

AB  - In order to reduce air pollution by green-house gases released during fossil fuels combustion, hydrogen has been suggested as an alternative, clean fuel [1]. The most promising method of obtaining green hydrogen (and oxygen) is electrolytic water splitting [2]. For splitting process to be efficient, it is necessary to useelectrocatalysts with high activity, but they should also be economically accessible. Ionic liquids are used in the most diverse fields of sciencedue to their unique physical and chemical properties, and in this regard, they can be used for the development of electrocatalystsby direct carbonization [3].  Within this study, carbon catalysts doped with iron and copper (Fe/C, Cu/C and FeCu/C) were prepared by carbonization of ionic liquids containing the corresponding metal and characterized for the hydrogen evolution reaction (HER) in alkaline (8 M KOH) media. Electrochemical measurements were made by cyclic voltammetry (CV), linear cyclic voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA). All electrocatalysts showed good activity for HER. Tafel slope (b) values of -132, 155 and -151 mV dec-1 (Table 1) were obtained for HER at 25 oC for Fe/C, Cu/C and FeCu/C, respectively. Also, the exchange current density (j0) was determined and the values ranged from 1.28 to 2.94 10-2 mAcm-2. The results (Table 1) show that Fe/C, Cu/C and FeCu/Care promisingelectrocatalysts for hydrogen gas production by water splitting.

AB  - Porous cobalt (III) oxide (Co3O4) and mixed cobalt (III) oxide - tin oxide (Co3O4/SnO2) were prepared by a novel template-based hydrothermal method resulting in their spherical morphology as confirmed by thorough physico-chemical characterisation. Two oxides were systematically examined as bifunctional electrocatalysts for oxygen reduction (ORR) and evolution (OER) reaction in alkaline media by voltammetry with rotating disk electrode, electrochemical impedance spectroscopy, and chronoamperometry. Low-cost Co3O4 and Co3O4/SnO2 electrocatalysts showed excellent ORR performance with low onset and half-wave potential, low Tafel slope, and the number of exchange electrons near 4, comparable to the commercial Pt/C electrocatalyst. Low OER onset potential of 1.52 and 1.57 V was observed for Co3O4 and Co3O4/SnO2, respectively, with low charge transfer resistance under anodic polarization conditions. Finally, to test bifunctional activity and durability of the two electrocatalyst, switch OER/ORR test was carried out.

AB  - The catalytic activity of five silver-polyaniline-polyvinylpyrrolidone (Ag@PANI@PVP1–5) nanocomposites for borohydride oxidation reaction (BOR) was thoroughly examined. The nanocomposites were synthesized by an in situ chemical oxidative polymerization of aniline monomer by Ag+ ions in the presence of accelerator – PVP and physicochemical properties were determined prior their use in electrocatalysis. Ag@PANI@PVP3 with 35.4 wt% Ag delivered the highest current density and specific current density during BOR. Evaluation of the order of reaction < 1 suggested indirect BOR mechanism. Furthermore, Ag@PANI@PVP3 also delivered the highest current density and stable performance during chronoamperometric study of BOR. Its apparent activation energy of 15 kJ mol−1 was found to be the lowest among the studied materials accounting for the high current densities. © 2023 The Author(s)

AB  - Direct liquid fuel cells represent one of the most rapidly emerging energy conversion devices. The main challenge in developing fuel cell devices is finding low-cost and highly active catalysts. In this work, PET bottle waste was transformed into nitrogen-doped graphene (NG) as valuable catalyst support. NG was prepared by a one-pot thermal decomposition process of mineral water waste bottles with urea at 800 °C. Then, NG/Pt electrocatalysts with Pt loadings as low as 0.9 wt.% and 1.8 wt.% were prepared via a simple reduction method in aqueous solution at room temperature. The physical and electrochemical properties of the NG/Pt electrocatalysts are characterized and evaluated for application in direct borohydride peroxide fuel cells (DBPFCs). The results show that NG/Pt catalysts display catalytic activity for borohydride oxidation reaction, particularly the NG/Pt_1, with a number of exchanged electrons of 2.7. Using NG/Pt composite in fuel cells is anticipated to lower prices and boost the usage of electrochemical energy devices. A DBPFC fuel cell using NG/Pt_1 catalyst (1.8 wt.% Pt) in the anode achieved a power density of 75 mW cm−2 at 45 °C. The exceptional performance and economic viability become even more evident when expressed as mass-specific power density, reaching a value as high as 15.8 W mgPt−1.

AB  - Zeolite ZSM-5 and zeolite β were modified by aqueous ion exchange with cerium and then calcined (cal) to obtain Ce-ZSM-5, Ce-ZSM-5 cal, Ce-β, and Ce-β cal electrocatalysts. X-ray powder diffraction analysis, Fourier Ttransform infrared spectroscopy, scanning electron microscopy with energy dispersive spectroscopy, X-ray photoelectron spectroscopy, fluorescence spectroscopy, and Brunauer-Emmett-Teller method revealed changes in the structure and porosity of zeolites upon calcination. Voltammetry, chronoamperometry, and electrochemical impedance spectroscopy were used for testing four zeolites for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) in alkaline media. OER starts the earliest at Ce-β cal with onset overpotential 50, 70, and 110 mV lower than Ce-ZSM-5 cal, Ce-ZSM-5, and Ce-β. Ce-β cal further showed the lowest OER Tafel slope (114 mV dec− 1 ). Consequently, the highest OER current density was recorded in the case of Ce-β cal, followed by Ce-β, Ce-ZSM-5 cal, and Ce-ZSM-5. Regarding ORR, Ce-ZSM-5 cal showed the lowest Tafel slope (70 mV dec− 1 ) with the highest current densities that remained constant during the chronoamperometry test with a negligible decrease of 4%. It could be concluded that calcined forms exhibit better performance for OER and OER than their parent, non-calcined forms due to more active sites available for OER/ORR and decreased charge-transfer resistance.

AB  - Electrochemical water dissociation involves two reactions: the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), at the cathode and anode, respectively [1]. Water electrolysis could be sustainable and clean production of hydrogen as fuel, but HER and OER rates need to be improved for industrial applications. The OER involves the transport of four electrons which requires a high overvoltage to reach a satisfactory current density [1].  OER:      4OH- → 2H2O + O2 + 4e- Numerous studies have been focused on synthesizing high-performance and low-cost anode materials [2]. Metal oxides and metal chalcogenides are recognized as promising electrocatalysts for OER [3]. They can be synthesized using various methods with a wide range of precursors. Herein cobalt (III) oxide (Co3O4) and cobalt (III) oxide combined with tin oxide (Co3O4/SnO2) were examined for OER in alkaline media by linear sweep voltammetry (LSV). A three-electrode system was used for electrochemical examination where saturated calomel electrode (SCE) and graphite rod were set as reference and counter electrodes, while Co3O4 and Co3O4/SnO2 were used as the working electrodes. All potentials in this paper were given versus reversible hydrogen electrode (RHE). Fig. 1 shows OER polarization curves of Co3O4 and Co3O4/SnO2 electrocatalysts in alkaline media where both electrocatalysts showed high OER activity. Still, Co3O4/SnO2 gave an almost three times higher OER current density of 98 mA cm-2 than Co3O4 electrocatalyst (30 mA cm-2) at 1.85 V. Tafel slopes were found to be 207 and 156 mV dec-1 for Co3O4 and Co3O4/SnO2 electrocatalysts, respectively. A lower slope means that less overpotential is required to get a high current. In this case, Co3O4/SnO2 has a lower Tafel’s slope which indicates synergetic effect of coupling two metal oxides when it comes to electro-oxidation of oxygen in alkaline media [1]. The iridium (IV) and ruthenium (IV) oxides (IrO2 and RuO2) as the best OER electrocatalysts but with low OER durability and high cost [1] could potentially be replaced with here tested Co3O4 and Co3O4/SnO2 electrocatalysts because of their low-cost synthesis, and high OER activity in alkaline media.

AB  - Gold polypyrrole (AuPPy) and copper polypyrrole (CuPPy) nanocomposites were prepared by a simple one-step in situ oxidative polymerization of pyrrole monomer by Au3+ and Cu2+ ions. Owing to their characteristic physicochemical properties confirmed by optical and structural characterization methods, the behavior of these materials as electrocatalysts for borohydride oxidation reaction (BOR) was considered. BOR apparent activation energy was found to be 16 and 22 kJ mol−1 for AuPPy and CuPPy electrocatalyst, respectively. The stability of the two electrocatalysts was assessed by chronoamperometry. Moreover, fuel cell tests were carried out with AuPPy and CuPPy as anode electrocatalyst of a direct borohydride-peroxide fuel cell (DBPFC). Open circuit voltage (OCV) of 1.30 V was obtained with both AuPPy and CuPPy, with the OCV increasing to 1.45 V upon adding a small amount of carbon (AuPPy-C). The peak power density of a DBPFC with BOR at AuPPy-C anode and hydrogen peroxide reduction reaction at Pt cathode was found to be ca. 162 mW cm−2 at 65 °C.

AB  - Development of cost-effective, bi-functional carbon electrocatalysts via direct carbonization of ionic liquids (bis(cholinium) tetrachlorocobaltate(II) ([Ch]2[CoCl4]) and bis(1-butyl-3-methylimidazolium) tetrachlorocobaltate(II) ([Bmim]2[CoCl4])) is reported herein for the first time. Carbon electrocatalysts, dual-doped with cobalt and nitrogen, were tested for oxygen reduction (ORR) and oxygen evolution (OER) reactions. Both materials show high bi-functional catalytic activity and excellent stability due to synergistic effects arising from the presence of nitrogen and cobalt. Electrocatalyst prepared by carbonization of [Ch]2[CoCl4] show exceptional activity and selectivity toward ORR. Conversely, electrocatalyst prepared from [Bmim]2[CoCl4] showed a slightly better OER performance indicating that different catalytic sites are responsible for O2 reduction and H2O oxidation. Parent CoO particles with graphitic nitrogen boost activity for ORR, while elemental Co supported by nitrogen atoms is responsible for OER activity. Finally, energy consumption during electrolytic oxygen production was calculated revealing energy saving when using two materials as anode electrocatalysts.

AB  - Nanocomposites of gold nanoparticles (AuNPs) and conducting polymers, polypyrrole (PPy) and polyaniline (PANI), were prepared by simple oxidative polymerization of the corresponding monomer (pyrrole and aniline, respectively) by tetrachloroauric acid. Au nanospheres and nanorods were formed in the case of Au@PPy and Au@PANI, respectively. Detection of As(III) using Au@polymer was investigated where both nanocomposites showed similar activity for As electrooxidation in acidic media. The activity of Au@PPy was notably improved upon the addition of a small amount of conducting carbon, giving higher current densities compared to the commercial Au electrode. Further optimization of the operational conditions including electrolyte composition, deposition time and potential, was carried out to reach the limit of quantification as low as 2 ppb. Au@PPy nanocomposite proved to be suitable for sensing of As(III) in the presence of other ions, such as Cu(II). Furthermore, it proved to be suitable for As(III) sensing in real samples.

AB  - Three different carbon-supported metal (gold, platinum, nickel) nanoparticle (M/c-IL) electrocatalysts are prepared by template-free carbonization of the corresponding ionic liquids, namely [Hmim][AuCl4 ], [Hmim]2 [PtCl4 ], and [C16mim]2 [NiCl4 ], as confirmed by X-ray diffraction analysis, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy and Raman spectroscopy. The electrochemical investigation of borohydride oxidation reaction (BOR) at the three electrocatalysts by cyclic voltammetry reveals different behavior for each material. BOR is found to be a first-order reaction at the three electrocatalysts, with an apparent activation energy of 10.6 and 13.8 kJ mol−1 for Pt/c-IL and Au/c-IL electrocatalysts, respectively. A number of exchanged electrons of 5.0, 2.4, and 2.0 is obtained for BOR at Pt/c-IL, Au/c-IL, and Ni/c-IL electrodes, respectively. Direct borohydride-peroxide fuel cell (DBPFC) tests done at temperatures in the 25–65◦C range show ca. four times higher power density when using a Pt/c-IL anode than with an Au/c-IL anode. Peak power densities of 40.6 and 120.5 mW cm−2 are achieved at 25 and 65◦C, respectively, for DBPFC with a Pt/c-IL anode electrocatalyst. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

abstract = "Three different carbon-supported metal (gold, platinum, nickel) nanoparticle (M/c-IL) electrocatalysts are prepared by template-free carbonization of the corresponding ionic liquids, namely [Hmim][AuCl4 ], [Hmim]2 [PtCl4 ], and [C16mim]2 [NiCl4 ], as confirmed by X-ray diffraction analysis, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy and Raman spectroscopy. The electrochemical investigation of borohydride oxidation reaction (BOR) at the three electrocatalysts by cyclic voltammetry reveals different behavior for each material. BOR is found to be a first-order reaction at the three electrocatalysts, with an apparent activation energy of 10.6 and 13.8 kJ mol−1 for Pt/c-IL and Au/c-IL electrocatalysts, respectively. A number of exchanged electrons of 5.0, 2.4, and 2.0 is obtained for BOR at Pt/c-IL, Au/c-IL, and Ni/c-IL electrodes, respectively. Direct borohydride-peroxide fuel cell (DBPFC) tests done at temperatures in the 25–65◦C range show ca. four times higher power density when using a Pt/c-IL anode than with an Au/c-IL anode. Peak power densities of 40.6 and 120.5 mW cm−2 are achieved at 25 and 65◦C, respectively, for DBPFC with a Pt/c-IL anode electrocatalyst. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

AB  - Cerium oxide (CeO 2-δ ) ultrafine nanoparticles, with the lower (CeO 2-δ -HT) and higher (CeO 2-δ -SS) fraction of oxygen vacancies, were used as anchoring sites for the polymerization of aniline in acidic medium. As a result, polyaniline-emeraldine salt (PANI-ES)-based composites (PANI-ES@CeO 2-δ -HT and PANI-ES@CeO 2-δ -SS) were obtained. The interaction between CeO 2-δ and PANI was examined by FTIR and Raman spectroscopy. The PANI polymerization is initiated via electrostatic interaction of anilinium cation and Cl − ions (adsorbed at the protonated hydroxyl groups of CeO 2-δ ), and proceeds with hydrogen and nitrogen interaction with oxide nanoparticles. Tailoring the oxygen vacancy population of oxide offers the possibility to control the type of PANI-cerium oxide interaction, and consequently structural, electrical, thermal, electronic and charge storage properties of composite. A high capacitance of synthesized materials, reaching ∼294 F g −1 (PANI-ES), ∼299 F g −1 (PANI-ES@CeO 2-δ -HT) and ∼314 F g −1 (PANI-ES@CeO 2-δ -SS), was measured in 1 M HCl, at a common scan rate of 20 mV s −1 . The high adhesion of PANI with cerium oxide prevents the oxide from its slow dissolution in 1MHCl thus providing the stability of this composite in an acidic solution. The rate of electrochemical oxidation of emeraldine salt into pernigraniline was also found to depend on CeO 2-δ characteristics. © 2019 Elsevier Ltd

AB  - Two gold nanorod-polyaniline (Au-PANI) composites with different contents of Au were prepared by two methods. An ex situ method, in the presence of preformed gold nanorods (AuNRs) and in situ one, when an AuNRs and PANI matrix is produced simultaneously, were used. Both methods were performed in immiscible water/toluene biphasic system as a simple interfacial polymerization process. Optical, structural and morphological characteristics of the formed nanocomposites were identified. It was found that AuNRs are embedded in the conducting emeraldine salt form of PANI. Nanocomposites containing 2.0 and 28.9 wt% of Au were subsequently systematically studied for borohydride oxidation reaction (BOR) for potential application in direct borohydride-peroxide fuel cell (DBPFC). Reaction parameters: number of electrons exchanged, order of reaction and activation energy, were evaluated. Both Au-PANI nanocomposites showed activity for BOR. A laboratory DBPFC was tested reaching specific peak power density of 184 Wg(-1) at 65 degrees C with Au-PANI 1 nanocomposite (containing only 2.0 wt% of Au) as anode.

AB  - This work shows the potential application of carbon materials prepared by three different ionic liquid-based methods, using 1-butyl-3-methylimidazolium methanesulfonate [bmim][MeSO3], for electrochemical supercapacitors. The effects of [bmim][MeSO3] on morphology, texture and surface chemistry of prepared materials has been explored by SEM/TEM, N2/CO2 adsorption measurements and XPS. The results indicate the possibility of synthesis of carbon materials with tunable physicochemical properties using ionic liquid based methods. The charge storage behavior of all materials was studied in three different pH aqueous electrolytes. The pseudocapacitive and double layer contributions were estimated and discussed from the aspect of the textural changes and the changes of the chemical composition of surface functional groups containing heteroatoms. C[dbnd]O type functional groups, with the contribution of COOH groups, were found to be responsible for a different amount of charge, which could be stored in alkaline and acidic electrolytic solution. The material prepared by direct carbonization of [bmim][MeSO3], showed the best electrochemical performance in alkaline electrolyte with a capacitance of 187 F g−1 at 5 mV s−1 (or 148 F g−1 at 1 A g−1), due to the contribution of both electric-double layer capacitance and pseudocapacitance which arises from oxygen, nitrogen and sulfur functional groups. © 2018 Elsevier Ltd

AB  - Carbon materials, prepared by using different methods with ionic liquids, are compared as electrocatalysts for the oxygen reduction reaction (ORR). Materials were synthesized through the hydrothermal carbonization of glucose and by using the same method in the presence of 1-butyl-3-methylimidazolium methanesulfonate [bmim][MeSO3] as an additive. Another two carbon-based materials were prepared by using ionic-liquid-based methods: ionothermal carbonization of glucose using [bmim][MeSO3] as a recyclable medium for the carbonization reaction and by direct carbonization of the ionic liquid in a one-step method using [bmim][MeSO3] as the precursor for N- and S-doped porous carbon (Carb-IL). Characterization results showed the possibility of morphology and porosity control by using [bmim][MeSO3]. All materials were subsequently tested for the ORR in alkaline media. Carb-IL showed enhanced and stable electrocatalytic ORR activity, even in the presence of methanol, ethanol, and borohydride, opening the possibility for its application in fuel cells.

AB  - Palladium ion-exchanged zeolite X (PdX) was prepared by zeolite impregnation with palladium acetylacetonate, followed by thermal degradation of the salt. PdX was characterised using SEM-EDS, ICP-OES and XRD. Analysis revealed presence of 7.78 wt.% of Pd in the form of PdO. Subsequently, PdX was tested for hydrogen evolution reaction (HER) in alkaline medium using linear scan voltammetry, chronoamperometry and electrochemical impedance spectroscopy measurements. The influence of addition of carbon black on the materials catalytic performance was also investigated. The HER kinetic parameters, including Tafel slope, exchange current density and activation energy, were determined. In order to provide atomic-level insights, experimental results were complemented by density functional theory calculations. It is suggested that favourable hydrogen adsorption energetics on PdO is responsible for efficient HER catalysis by this novel electrocatalyst. (c) 2017 Elsevier Ltd. All rights reserved.

AB  - Monitoring bromides (Br-) is of crucial importance since bromates, potential human carcinogens, are formed during ozonation of water containing bromides in concentrations GT 100 mu gL(-1). Within this study, silver (Ag) and four carbon-supported Ag catalysts were synthesized by the gamma-radiation method and their morphology and structure examined using transmission electron microscopy, X-ray diffraction, and UV-Vis analysis. The nanocatalysts were tested for Br- sensing in aqueous media using cyclic voltammetry. All five Ag materials exhibited electroactivity for sensing of Br- ions, with pure Ag catalyst giving the best response to Br- ions presence in terms of the lowest limit of detection. Sensing of bromides was also explored in tap water after addition of bromides suggesting that herein prepared catalysts could be used for bromides detection in real samples. Furthermore, sensing of other halogen ions, namely, chlorides and iodides, was examined, and response due to chloride presence was recorded.

AB  - Carbon-supported silver nanoparticles (Ag:NPs/C) were synthesized by gamma irradiation-induced reduction method using the poly(vinyl alcohol) or poly(vinyl alcohol)/chitosan polymer as stabilizer. Prepared samples were characterized using transmission electron microscopy and X-ray diffractometry. Subsequently, Ag:NPs/C were studied using rotating disc and rotating ring disc method as electrocatalysts for ORR (oxygen reduction reaction) and BOR (borohydride oxidation reaction) for potential application in alkaline fuel cells. The synthesis method used herein offers simple and fast approach for catalytic ink preparation, since the ink is prepared in one-step radiation process, simultaneously with Ag+ ions reduction. Very high and stable catalytic efficiency toward ORR via 4e(-) path was evidenced during 4000 square pulse polarization cycles. BOR, accompanied with the simultaneous borohydride ion hydrolysis, was found to proceed at the oxidized Ag surface. (C) 2016 Elsevier Ltd. All rights reserved.

AB  - Electrodes based on composites of zeolites with carbonized polyaniline prepared in the presence of 5-sulfosalicylic acid are evaluated for both qualitative and quantitative determination of phenols in aqueous solutions. Zeolites used included NaX and NaY, as well as their transition metal (Mn and Cu) cation-exchanged forms, and they were all characterized usingXRPD, FTIR and SEM. Cyclic voltammetry was used to study composites electrochemical response in the presence of p-nitrophenol, phenol and 5-aminophenol in acidic, neutral and al- kaline media. Linear dependence of current on p-nitrophenol concentration in acidic media was obtained in 0.11 mM concentration range. The comparative evaluation of the electrochemical response of NaX/carbonized polyaniline composite and its individual components revealed significantly lower limit of detection obtained using composite electrode (1.27 mu M) compared to that obtained using pure zeolite (135 mu M) or pure carbonized polyaniline (94.5 mu M) electrode. Composite electrode gave response to p-nitrophenol presence in neutral media as well, but it quickly disappeared with continuous scanning, while no clear response could be seen in highly alkaline media. Thus, this work demonstrates benefits of using novel composite based on zeolites and carbonized polyaniline for sensing of phenols in acidic aqueous solutions. (C) 2016 Elsevier B.V.
