AB  - Pure and a series of Fe3+ doped zirconia nanopowders were synthesized combining colloidal chemistry and solvothermal method from organometallic precursors in order to correlate doping and properties of zirconia matrix. After annealing of washed nanopowders at 600 °C, detailed characterization was performed using X-ray diffraction, UV/Vis absorption and luminescence, infrared and electron paramagnetic spectroscopy, transmission electron microscopy and BET measurements. Zirconia samples had mixed monoclinic and tetragonal crystalline phase; increasing Fe3+ ions concentration was followed by increasing of tetragonal phase share. In the sample with highest Fe3+ concentration, hematite can be detected. Also, UV/Vis spectrophotometry showed that Fe3+ doping lowers effective band gap of zirconia matrix from 4.5 eV (bulk value) to 2.1 eV for doped/nanocomposite samples. EPR measurements proved presence of dopant and showed that isolated Fe3+ ions in zirconia matrix exist in both crystalline phases; monoclinic and tetragonal (g 4.8 and g 4.27–4.2, respectively) surroundings. Zirconia samples were also successfully used as photocatalysts for photocatalytic degradation of 2, 4, 6, trichlorophenol. © 2019 Elsevier Ltd and Techna Group S.r.l.

The estimated band-gap energy of synthesized sample is in the visible spectral region and has a value of about 2.25 eV. Photocatalytic properties of synthesized sample are probed in photocatalytic degradation of three selected dyes different in nature and structure, Rhodamine B (RhB), Methylene blue (MB) and Methyl orange (MO), under the illumination with simulated Solar light. Obtained results revealed that photocatalytic degradation of RhB and MO is mainly result of synergic effect of photogenerated holes and oxygen, while primary effect in ZnIn2S4/MB system is bleaching of the dye, but no photodegradation was observed. © 2019 Elsevier B.V.

AB  - A serie of novel ZrO2/Polyaniline (PANI) hybrid nanocomposite powders were successfully synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate (APS) in water, in the presence of ZrO2 nanoparticles. Syntheses were performed at initial ZrO2/aniline mole ratios 50,100 and 150 to produce ZP-50, ZP-100 and ZP-150. The morphological, structural, and optical properties of the synthesized nano composites were studied using Transmission electron microscopy (TEM), X-ray powder diffraction (XRD), Raman, UV-Vis and Electron-paramagnetic resonance (EPR) spectroscopies. EPR spectra of ZP-50 and ZP-100 nanocomposites showed the presence of intensive peak at the g-values comparable to that for free electrons (2.0023) indicating the presence of oligo/poly (semiquinone radical cations), i.e. polarons as charge carriers in PANI part; ZP-150 showed weak polaron peak of PANI, and peak that can be assigned to defects in zirconia matrix (Zr3+, oxygen vacancies). The monoclinic crystal structure of ZrO2 nanoparticles in all nanocomposites was confirmed by XRD and by Raman spectroscopy. The photocatalytic activities of ZP nanocomposites were evaluated using the photocatalytic degradation of trichlorophenol (TCP) and Rhodamine B model compounds and compared with the activity of bare ZrO2 nanoparticles. Enhanced degradation efficiencies of nanocomposites regarding TCP degradation were observed. (C) 2017 Elsevier B.V. All rights reserved.

AB  - Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM techniques were used for structural and morphological characterization of obtained samples. XPS spectra of mixed oxide samples were compared in order to correlate composition of samples with surface properties and presence of defects. Relative positions of defect states within band-gaps of semiconductors were estimated from UCPL spectra. UV-Vis DRS spectra revealed that both pure oxides experienced red shift of absorption thresholds compared to reference data. Photocatalytic activities of all samples were probed under simulated Solar light on three model compounds: phenol, 4-chlorophenol (4-CP) and 2, 4, 6-trichlorphenol (TCP). Pure TiO2 showed the highest photocatalytic activity in the case of phenol. However, pure ZrO2 and binary oxides showed higher photoactivity in degradation of 4-CP and TCP. The activity of wide band-gap semiconductors under simulated Solar light in photodegradation of phenol and its derivatives is most probably the consequence of formation of charge transfer complexes between pollutant molecules and semiconductors surface.

AB  - Nitrogen-doped TiO2 (N-TiO2) is considered as one of the most promising materials for various photocatalytic applications, while noble metals Pd and Pt are known as good catalysts for hydrogen evolution. This work focuses on the determination of structural and electronic modifications of N-TiO2, achieved by noble metal deposition at the surface, as a starting indicator for potential applications. We focus on the properties of easily synthesized nanocrystalline nitrogen-doped anatase TiO2, modified by depositing small amounts of Pd (0.05 wt%) and Pt (0.10 wt%), aiming to demonstrate efficient enhancement of optical properties. The chemical states of dopants are studied in detail, using X-ray photoemission spectroscopy, to address the potential of N-TiO2 to act as a support for metallic nanoparticles. DFT calculations are used to resolve substitutional from interstitial nitrogen doping of anatase TiO2, as well as to study the combined effect of nitrogen doping and oxygen vacancy formation. Based on the binding energies calculated using Slaters transition state theory, dominant contribution to the N 1s binding energy at 399.8 eV is ascribed to interstitially doped nitrogen in anatase TiO2.

abstract = "Nitrogen-doped TiO2 (N-TiO2) is considered as one of the most promising materials for various photocatalytic applications, while noble metals Pd and Pt are known as good catalysts for hydrogen evolution. This work focuses on the determination of structural and electronic modifications of N-TiO2, achieved by noble metal deposition at the surface, as a starting indicator for potential applications. We focus on the properties of easily synthesized nanocrystalline nitrogen-doped anatase TiO2, modified by depositing small amounts of Pd (0.05 wt%) and Pt (0.10 wt%), aiming to demonstrate efficient enhancement of optical properties. The chemical states of dopants are studied in detail, using X-ray photoemission spectroscopy, to address the potential of N-TiO2 to act as a support for metallic nanoparticles. DFT calculations are used to resolve substitutional from interstitial nitrogen doping of anatase TiO2, as well as to study the combined effect of nitrogen doping and oxygen vacancy formation. Based on the binding energies calculated using Slaters transition state theory, dominant contribution to the N 1s binding energy at 399.8 eV is ascribed to interstitially doped nitrogen in anatase TiO2. Given that both structure and photocatalytic properties depend greatly on the synthesis procedure, this work contributes further to establishing correlation between the structure and optical properties of the noble metal modified N-TiO2 system.",

The doping of TiO2 induced a shift in the absorption threshold towards the visible spectral range, compared to pure titania. The process of annealing induced an increase in crystallinity and particle sizes in the obtained materials.

AB  - We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporated Si4+ ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powders were annealed at 600 degrees C and characterized using structural (XRD), morphological (SEM and TEM) and optical techniques (UV/vis DR, FTIR and photoluminescence spectroscopy). Their textural properties (BET method) and photocatalytic activity toward degradation of model compounds (tricholophenol and Rhodamine B) using simmulated solar light were obtained. We showed that by using hydrothermal synthesis method pure monoclinic ZrO2 highly crystalline powder can be obtained. Incorporation of Si4+ ions induced stabilization of tetragonal crystalline phase at room temperature and decreasing of particle sizes. Incorporation of Si4+ ions in zirconia matrix also resulted in increase of specific area of nanopowders. FTIR measurements were used as proof for existence of Zr-O-Si bond. Effective band gap of zirconia powders was reduced from 5 (pure ZrO2) to 3.8 eV for samples with Si4+ ions. All zirconia powders showed significant photocatalytic activity regarding degradation of triclorophenol and no activity regarding RB (Rhodamine B dye). Photocatalytic activity of zirconia was increased by incorporation of Si ions in the host matrix. The source of this observation is discussed correlating all obtained properties of pure and Si-incorporated nanopowders. Optimization of synthesis parameters and composition of zirconia samples obviously can lead to their photocatalytic activity comparable to Degussa TiO2 powder, famous and commercial photocatalyst.

AB  - ZnO spheroidal nanoparticles, synthesized by microwave processing, were used for preparation of composites with polyethylene oxide (PEO). The phase purity and crystal structure of the composites were investigated by X-ray diffraction (XRD) and Raman spectroscopy. The composites particles morphology and size distributions were studied by FE-SEM and laser diffraction particle size analyzer, respectively. The optical properties were studied using UV Vis diffuse reflectance and photoluminescence spectroscopy. It is found that in the wavelength range 550-800 nm, ZnO and ZnO/PEO composites absorb about 50% of the incident light intensity. Also red-shift of band gap energy (0.12-0.15 eV) compared to bulk ZnO was determined. The effect of PEO molecular weights, 200,000, 600,000 and 900,000 g/mol, on photocatalytic activity of ZnO/PEO composites were examined via de-colorization of methylene blue (MB) under direct sunlight irradiation. A large efficiency of MB de-colorization was found after 6 h of irradiation. The enhanced photocatalytic activity of ZnO/PEO composites is attributed to the: (1) lattice defects introduced in ZnO crystal structure by rapid microwave processing, and (2) presence of PEO as a source of oxygen interstitials. In order to confirm and further clarify the experimental results ab initio calculations based on density functional theory (DFT) were performed. (C) 2016 Elsevier Ltd. All rights reserved.

AB  - Sensitization of TiO2 crystals and nanoparticles with appropriately chosen organic molecules can lead to a significant shift of their absorption threshold from the UV to the visible, thus improving the absorption of the solar spectrum as well as the efficiency of photocatalytic and photovoltaic devices. Herein, the surface modification of nanocrystalline TiO2 particles (45 angstrom) with salicylate-type ligands consisting of an extended aromatic ring system, specifically 1-hydroxy-2-naphthoic acid and 1,4-dihydroxy-2-naphthoic acid, was found to alter the optical properties of nanoparticles in a similar way to salicylic acid. From both absorption measurements and steady-state quenching measurements of modifier fluorescence upon binding to TiO2 in methanol/ water = 90/10 solutions, stability constants in the order of 10(3) M-1 have been determined at pH 2. Fluorescence lifetime measurements, in the presence and absence of colloidal TiO2 nanoparticles, indicated that the fluorescence quenching process is primarily static quenching, thus proving the formation of a nonfluorescent charge-transfer (CT) complex. The binding structures were investigated by using FTIR spectroscopy. Thermal stability of CT-complexes was investigated by using TPD analysis (TG/DTA/MS). Quantum chemical calculations on model systems using density functional theory (DFT) were performed to obtain the vibrational frequencies of charge transfer complexes, and the calculated values were compared with the experimental data. The investigated ligands have the optimal geometry for binding to surface Ti atoms, resulting in ring coordination complexes of a salicylate type (binuclear bidentate binding-bridging) thus restoring the six-coordinated octahedral geometry of surface Ti atoms. The formation of the inner-sphere CT-complexes results in a red shift of the semiconductor absorption compared to unmodified nanocrystallites and a reduction in the band gap upon the increase in the electron delocalization when including an additional ring.

AB  - A hot-injection method for the synthesis of CdIn2S4 in three different compositions of organic media/solvents was studied. Nanosized CdIn2S4 is successfully synthesized in an oleic acid/oleylamine mixture of complexing/capping agents. The obtained mesocrystals of 20-30 nm in diameter are self-organized in marigold-like structures. The estimated band-gap of synthesized semiconductor is in the visible spectral region and has a value of about 2.1 eV. The potential of the band edges is calculated using an empirical equation. The as-prepared material was successfully transferred from organic to aqueous media by using 2-mercaptoethanol in a surface ligand exchange process. Using a similar synthetic procedure, ZnIn2S4 synthesis was performed. The obtained materials were characterized using UV/vis spectroscopy, XRD and TEM. Formation and growth mechanisms of the synthesized materials are proposed.

AB  - We report a simple colloidal synthesis of two types of Sb2S3 nanowires with small band gap and high aspect ratio. Field-emission scanning electron and transmission electron microscopies confirmed formation of high aspect ratio Sb2S3 nanowires, separated in the form of bundles and coalesced with each other in long bars. Diffuse reflectance and absorption spectroscopies revealed that the optical band-gap energies of the synthesized nanowires separated in the form of bundles are 1.56 and 1.59 eV, and coalesced with each other in long bars are 1.36 and 1.28 eV, respectively. The structure refinement showed that Sb2S3 powders belong to the orthorhombic structure with space group Pnma (no. 62). It was found that Sb2S3 nanowires separated in the form of bundles predominantly grow along the [0 1 0] direction being in the needle-like shape. The nanowires coalesced with each other in long bars rise in the form of long bars, are ribbon-like in shape and have expressed {1 0 1} facets which grow along the [0 1 0] direction. No peaks in photoluminescence spectra were observed in the spectral range from 250 to 600 nm. In order to shed more light on the experimental results concerning the band-gap energies and, in the literature generally poorly investigated electronic properties of the synthesized material, we performed theoretical calculations of the electronic structure and optical properties of the Sb2S3 samples synthesized here. This was done on the basis of density functional theory with the generalized gradient approximation, and also with an improved version of the exchange potential suggested recently by Tran and Blaha. The main characteristic is the significant improvement of the band gap value.

AB  - Samples of AgInS2 and CuInS2 nanoparticles were synthesized by hot-injection method at 270 degrees C using 1-dodecanethiol (DT) and elemental sulphur (S) as sulphide precursors, and oleylamine as reaction medium and surfactant. Composition, crystal structure, and particle size of obtained materials were tracked by XRD and TEM/HRTEM measurements. It was shown that, due to its dual role as sulphur source and surfactant, DT drastically slows formation of desired material. Samples obtained with DT even after 4 h of reaction have traces of intermediary compound (beta-In2S3), whereas in samples synthesized with elemental S these traces are less pronounced. The growth mechanism and influence of each reaction step are discussed in detail.

AB  - We report the novel colloidal syntheses in organic media of antimony sesquioxide (Sb2O3) spherical nanoparticles (30-250 nm) and octahedron micro- and nanocrystals (100 nm-4 mu m) depending on the synthetic method conditions. It is observed that small differences in the synthetic procedure cause large differences in the very changeable morphology. The structure of Sb2O3 powders was refined down to the R-factors of 9.57, 7.44, 9.19, 9.78, and 8.30 %. The refinement showed that Sb2O3 powder belongs to the cubic crystal type with space group Fd (3) over barm (No. 227). The values of estimated standard deviations, as well as reliability factors, confirmed that the structure of Sb2O3 was well refined. Ultraviolet and visible (UV-Vis) absorption spectroscopy and diffuse reflectance measurements (DRS) reveal that the optical band gap energies found for the Sb2O3 octahedrons and nanoparticles, micro- and nanocrystals, respectively, are quite independent of the synthetic method conditions and synthesized morphology and is found to be between 4.1-4.4 eV. No peaks in both photoluminescence (PL) emission and excitation spectra have been observed for a broad spectral range, typical for this material. In order to discriminate between conflicting experimental results concerning the band gap energy of this compound, we investigated theoretically the electronic structure and optical properties of one of the cubic sesquioxide Sb2O3 samples synthesized here. This has been done on the basis of density functional theory (DFT) with the generalized gradient approximation (GGA) and improved version of exchange potential suggested recently by Tran and Blaha (TB-mBJ). The main characteristic of the calculated TB-mBJ electronic structure is the significant improvement of the band gap value, which is in perfect agreement with our experimental measurements. The real and imaginary parts of the dielectric tensor are also calculated and interpreted in terms of the obtained electronic structure.

AB  - Gd3+-doped titania nanoparticles have been synthesized via acidic hydrolysis of Gd3+ and Ti4+ organic precursors. The resulting products were characterized by X-ray diffraction, transmition electron microscopy and diffuse reflection spectra. Experimental results indicated that Gd3+-doping makes great impact on the optical properties and photocatalytic activity of the obtained TiO2 nanoparticles. All applied doping concentrations induced enhancement of photoactivity regarding degradation of Rhodamine B, compared to pure TiO2. The inter-band defect states formed as a result of incorporation of Gd3+ ions in the TiO2 matrix are most probably the cause of observed improved photoacatalytic activity and optical properties of the doped TiO2 nanoparticles.

AB  - Mechanical activation of precursors has been used for the preparation of Cr-doped sphene ceramic pigments (CaTi1-yCrySiO5). Ceramic material has been prepared from a powder mixture of CaCO3, TiO2, SiO2 and Cr(NO3)center dot 9H(2)O using vibro-milling for homogenization and activation of precursors. The mechanochemical process initially yielded amorphous powders, which on further calcination, crystallized to yield Cr-doped sphene ceramic pigment. Phase evolution in CaTi1-yCrySiO5 composition with thermal treatment was investigated by X-ray powder diffraction (XRPD). Texture properties and particle size distribution were analyzed by scanning electron microscopy (SEM) and laser diffraction, respectively. UV/Vis reflectance spectra are used to determinate the behavior of the chromium ion. The color efficiency of pigments was evaluated by colorimetric analysis (CIE L * a * b system). Photoluminescence measurements were also performed. (c) 2013 Elsevier B.V. All rights reserved.

AB  - Ternary chalcogenide nanoparticles, CuInS2 and CuInSe2, were synthesized in a high-temperature boiling non-polar organic solvent. X-Ray diffraction analysis revealed that both materials had a tetragonal (chalcopyrite) crystal structure. The morphology of the obtained materials was revealed by transmission electron microscopy. Agglomerated spherical CuInS2 nanoparticles with broad size distribution in the range from 2 to 20 nm were obtained. In the case of CuInSe2, isolated particles with a spherical or prismatic shape in the size range from 10 to 25 nm were obtained, as well as agglomerates consisting of much smaller particles with a diameter of about 2-5 nm. The particles with the smallest diameters of both materials exhibited quantum size effects.

AB  - In this paper we report the synthesis of antimony sulphide (Sb2S3) nanobars performed using a simple organo-colloidal synthetic method. The as-synthesised Sb2S3 nanobars with various precursor concentrations and heating times showed differences in the morphology (open and enclosing forms) and structural parameters. UV-vis absorption measurements revealed that the optical band gap energies lay in the red part of the solar spectrum. The observed band gap energies, of nearly the same values (similar to 1.6 eV), proved that precursor concentrations and heating times had no effect on them. The structure refinement showed that the Sb2S3 powder belonged to the orthorhombic type with a space group Pbnm. It was found that Sb2S3 nanobars predominantly grew along the [010] direction, and that the unit cell parameters and the preferred orientation parameter (tau) refined against experimental data were quite dependent on both the precursor concentration and the heating time. The optimum heating time to nicely follow the dependence of structural parameters on the precursor concentration was observed. (C) 2012 Elsevier B.V. All rights reserved.

AB  - In this work we present details of different synthesis procedures for preparation of ZnO powders and a possibility to create various particles morphology and average size; from micrometer rods to nanometer spherical particles. We studied two synthesis methods, low temperature hydrothermal processing (HT) and ultrasound processing (US). The morphology and average particle size of the ZnO particles were modified by adjusting the mole ratio of [Zn2+]/[OH] in the reactants solution. Agglomeration of the particles was prevented using a polyvinyl pyrrolidone (PVP) as a capping agent. The synthesized powders were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (FESEM) and UV-Vis - diffusion reflection spectroscopy (UV-Vis DRS). Based on the results of the scanning electron microscopy we proposed a possible growth mechanism of the ZnO particles depending on the mole ratio of [Zn2+]/[OH]. Also, we considered the influence of particle size and morphology on the optical properties of the prepared powders. The observed results sowed that the size and morphology of ZnO particles greatly affect the absorption of visible light (%) and the shift of the energy gap (eV).

Gold colloidal NPs were introduced into a PVA matrix by simple solution-casting method to obtain homogenous, transparent, and colored films. NPs and NC films with different contents of inorganic phase (0.7, 1.4, and 2.1 wt %) were characterized by UV/Vis and FTIR spectrophotometry. Dimensions of the colloidal NPs were obtained by TEM (d similar to 15 +/- 3 nm) and compared with results obtained by AFM of NC films. Comparison of thermal properties of the pure PVA and NC films showed that thermal stability is slightly reduced. DSC measurements revealed that T-g and melting temperatures of NCs are higher compared to pure PVA films.

AB  - Nanosized AgInSe2 particles (d similar to 7-25 nm) were synthesized using colloidal chemistry method at 270 degrees C. As solvents/surface ligands 1-octadecene, trioctylphosphine, and oleylamine were used. It was shown that choice of ligand has crucial impact not only on final crystal phase of nanoparticles, but also at mechanism of crystal growth. X-ray diffraction and TEM/HRTEM techniques were used to identify obtained crystal phases and to measure average size and shape of nanoparticles. UV/Vis data were used to estimate band-gap energies of obtained samples. It was shown that presented routes can provide synthesis of nanoparticles with desired crystal phase (tetragonal and/or orthorhombic), with band-gap energies in the range from 1.25 to 1.53 eV.

AB  - We report the first time as-synthesized antimony trisulfide (Sb2S3) nanowires with flower-like organization by using different oleic acid (OA)/2-ethylhexanoic acid (EHA) ratio. The resulting optical band-gap energy is 1.6 eV, and it is independent of the OA/EHA ratios. Sb2S3 nanowires grow predominantly along the [010] direction, and a significant decrease in unit cell parameters was observed. It seems that the shorter branched hydrocarbon chain leads to the better structural stability of the synthesized Sb2S3 nanowires.
