AB  - The attachment of squaric acid, a non-aromatic molecule, to the surface of TiO2 powder induced the optical absorption of the obtained hybrid material in the visible spectral range due to the interfacial charge transfer complex formation. The optical characterization of the hybrid is supported by the density functional theory calculations of the model cluster. The paramagnetic species generated upon excitation with ultraviolet or visible light, in both TiO2 powders, pristine and surface-modified, were identified conducting low-temperature solid-state and indirect electron paramagnetic resonance (EPR) spectroscopy experiments (spin trapping and spin scavenging). The solid-state EPR experiments indicated the promotion of electrons from the organic moiety to the titania conduction band under visible-light excitation of hybrid. Also, the spin scavenging experiments showed that the electrons generated in the hybrid upon the visible-light activation facilitate the reduction of the radical cations present in the dispersion, while these effects are not observed for pristine TiO2.

AB  - The efficiency of titanate-nanotubes-based photocatalysts towards hydrogen production was studied in the presence of the sacrificial agent, 2-propanol. The highest hydrogen production rate (~120 lmol h 1 g 1 ) was observed over surface-modified titanate nanotubes by 5-amino salicylic acid decorated with nanometer-sized silver nanoparticles. The X-ray diffraction analysis, transmission electron microscopy, nitrogen adsorption–desorption isotherms, and diffuse reflection spectroscopy were applied to characterize the prepared photocatalytic materials. The better photocatalytic performance of inorganic–organic hybrid materials in comparison to the pristine titanate nanotubes is a consequence of their improved light-harvesting ability due to the formation of interfacial charge transfer (ICT) complex, as well as the presence of metallic silver nanoparticles that suppress the recombination of photo-generated charge carriers. The spin trapping EPR experiments under irradiation of prepared photocatalysts with either UV or visible light were used to monitor the appearance of hydroxyl radicals and superoxide radical anions. The generation of superoxide radical anions under visible light irradiation was detected for hybrid materials, but not for the pristine titanate nanotubes. These results are a consequence of enhanced promotion ofelectrons to the conduction band due to extended absorption in visible spectral range in hybrids and support the higher efficiency of hydrogen generation observed for surface-modified titanate nanotubes by 5-amino salicylic acid decorated with silver nanoparticles.

AB  - Nickel-modified titanate/TiO2 catalysts were prepared by deposition of nickel ions onto hydrothermally prepared titanate supports, followed by hydrogen temperature-programmed reduction. Two different nickel precursors (hydroxide and carbonate) were used to tune reducibility and to vary the crystal phase structure of the final catalysts. The precursor reducibility and functional properties of the final catalysts were investigated systematically using various characterisation techniques. The results revealed a more facile reduction of the hydroxide precursor compared to its carbonate counterpart. Moreover, it was found that the formation of the anatase phase was favoured by the use of the hydroxide precipitation agent. The photocatalytic activity towards hydrogen production of the prepared catalysts was evaluated in the presence of 2-propanol under simulated solar light irradiation. A thorough study of the photocatalytic performance of the synthesised catalysts was conducted as a function of the precipitation agent used and the reduction temperature applied. The catalyst with dominant anatase crystal phase displayed the highest photocatalytic activity with a maximum H2 production rate of 1040 μmol h−1 g−1, this being more than four times higher than that of its carbonate counterpart. The catalysts with titanate structure showed similar activity, independent of the precipitation method used. The nanotubular structure was found to be the dominant factor in the stability of photocatalysts under long-run working conditions.

AB  - Surface modification of Al2O3 powders, prepared using reproducible sol-gel synthetic route with small colorless organic molecules, induces charge transfer complex formation and the appearance of absorption in the visible spectral region. Comprehensive microstructural characterization involving transmission electron microscopy, X-ray diffraction analysis, and nitrogen adsorption–desorption isotherms, revealed that γ-crystalline alumina powders consist of mesoporous particles in the size range from 0.1 to 0.3 μm, with specific surface area of 54.8 m2/g, and pore radius between 3 and 4 nm. The attachment of catecholate-type of ligands (catechol, caffeic acid, gallic acid, dopamine and 2,3-dihydroxy naphthalene), salicylate-type of ligands (salicylic acid and 5-amino salicylic acid), and ascorbic acid, to the surface such γ-Al2O3 particles leads to the formation of colored powders and activates their absorption in visible-light spectral region. To the best of our knowledge, similar transformation of an insulator (Al2O3), with the band gap energy of 8.7 eV, into a semiconductor-like hybrid material with tunable optical properties has not been reported in the literature before. The density functional theory (DFT) calculations with periodic boundary conditions were performed in order to estimate the energy gaps of various inorganic/organic hybrids. The calculated values compare well with the experimental data. The good agreement between the calculated and experimentally determined band gaps was found, thus demonstrating predictive ability of the theory when proper model is used.

AB  - Surface modification of CeO2 nano-powder, synthesized by a self-propagating room temperature method with
salicylate-type ligands (salicylic acid and 5-aminosalicylic acid) as well as catecholate-type ligands (catechol,
3,4-dihydroxybenzoic acid, caffeic acid and 2,3-dihydroxy naphthalene), induces the appearance of absorption in
the visible spectral region due to the interfacial charge transfer (ICT) complex formation. Thorough characterization
involving transmission electron microscopy, XRD analysis, and nitrogen adsorption-desorption isotherms,
revealed that loosely agglomerated CeO2 particles of the size ranging from 2 to 4 nm have cubic fluorite structure
and specific surface area of 140 m2/g. The attachment of salicylate- and catecholate-type of ligands to the surface
of CeO2 powders leads to the formation of colored powders with tunable absorption in the visible spectral region.
The density functional theory calculations with properly design model systems were performed to estimate the
alignment of energy levels of various inorganic/organic hybrids. A reasonably good agreement between calculated
values and experimental data was found.

AB  - Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B-6) was found to alter the optical properties. Microstructural characterization involving transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis revealed that the anatase TiO2 NPs had a narrow size distribution with an average diameter of 45 angstrom. The absorption onset of the surface-modified TiO2 samples was red-shifted by about 0.4 eV compared to the unmodified particles. The mode of binding between vitamin B-6 and the surface Ti atoms was investigated by Fourier transform infrared spectroscopy (FTIR). From the Benesi-Hildebrand plot, the stability constant of the surface complex was found to be of the order 10(2) M-1. The experimental findings were supported by detailed quantum chemical calculations based on the density functional theory (DFT). Agreement was found between the experimentally measured absorption spectra of the TiO2 NPs surface-modified with vitamin B-6 and the theoretically calculated electronic excitation spectra of the corresponding model system.

AB  - Antimicrobial performance of silver nanoparticles supported by functionalized hydroxyapatite with 5-aminosalycile acid was tested against Gram-negative bacteria E. coli, Gram-positive bacteria S. aureus and yeast C. albicans. Thorough characterization of materials (electron microscopy, nitrogen adsorption desorption isotherms, diffuse reflectance spectroscopy) followed each step during the course of nanocomposite preparation. Synthesized powder consists of rod-like hydroxyapatite particles (40-60 x 10-20 nm, length x diameter) decorated with nano-sized spherical silver particles whose content in nanocomposite was found to be 1.9 wt.-%. Concentration- and time-dependent bacterial reduction data indicated that use of silver nanoparticles even at concentration as low as 1 mu g mL(-1) lead to complete reduction of both bacteria (E. coli and S. aureus). On the other hand, non-toxic behavior of nanocomposite in broad concentration range (0.05-2.0 mg mL(-1)) was found towards C albicans. Successful inactivation of E. coli and S. aureus in five repeated cycles proved that synthesized nanocomposite can perform under long-run working conditions.

AB  - Under normal conditions, titanium dioxide does not absorb visible light photons due to large band gap. Nevertheless, when titanium dioxide nanoparticles (TiO2 NPs) are surface-modified with thiosalicylic acid (TSA), their optical properties are altered owing to the formation of charge transfer complex that initiates absorption in the visible spectral range. Colloidal and sol-gel techniques were used to synthesize uniform TiO2 NPs of different sizes (average diameters in the range 4-15 nm), and effects of their subsequent modification by TSA molecules were compared with effect of modification of commercial Degussa TiO2 powder. Thorough microstructural characterization of TiO2 nanoparticulates was performed including transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis, as well as nitrogen adsorption-desorption isotherms. Optical measurements revealed that all surface-modified TiO2 samples with TSA have similar spectral features independent of their morphological differences, and, more importantly, absorption onset of modified TiO2 samples was found to be red-shifted by 1.0 eV compared to the unmodified ones. The mode of binding between TSA and surface Ti atoms was analyzed by infrared spectroscopy. Finally, the quantum chemical calculations, based on density functional theory, were performed to support optical characterization of surface-modified TiO2 with TSA.

AB  - The biogenic hydroxyapatite (BHAP), obtained by proper treatment of bovine bones, was functionalized with 5-aminosalicylic acid (5-ASA). The coordination of 5-ASA to the surface of BHAP leads to the charge transfer (CT) complex formation accompanied with absorption in visible spectral range. The sorption ability of surface-modified BHAP with 5-ASA (5-ASA/BHAP) for removal of Pb2+ and Cu2+ ions from single- and bi-component solutions was compared with unmodified BHAP. The thorough characterization of both sorbents, BHAP and 5-ASA/BHAP, was performed including X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), nitrogen adsorption-desorption isotherms, as well as diffuse reflection spectroscopy.

AB  - The rod-like Ag2CO3 particles (2-4 3 0.3-0.6 mm, length 3 diameter) were synthesized in water by the precipitation reaction between AgNO3 and NaHCO3 in the presence of polyvinylpyrrolidone. The X-ray diffraction analysis revealed the co-existence of monoclinic and hexagonal phases of Ag2CO3, without presence of impurities. The band gap energy of Ag-2 CO3 was found to be 1.4 eV from the diffuse reflectance spectra. Photocatalytic ability of Ag2CO3 was tested using degradation reaction of the organic dye methylene blue over the wide range of concentrations, as well as under long run working conditions in repeated cycles. The photocatalytic mechanism was discussed in terms of the relative energetics of valence and conduction band. Antimicrobial efficiency of Ag-2 CO3 in dark was tested against Gram-negative bacteria E. coli. The Ag2CO3 dispersions in the concentration range 0.1-1.0 mg/mL ensured 100% reduction of bacteria cells. Time-dependent measurements revealed that reduction rates of bacteria cells vary in ascending order with the content of Ag2CO3. On the other hand, the observed reduction rates of bacteria cells do not depend on the concentration of coexisting free Ag+ ions (from 2 to 25 mg/L) present in Ag2CO3 dispersion.

The various microstructural (X-ray diffraction analysis, transmission electron microscopy, nitrogen adsorption desorption isotherms) and optical (diffuse reflection spectroscopy) techniques were used for thorough characterization of obtained heterostructures. The enhanced photocatalytic performance of AgX/Ag2CO3 heterostructures in comparison to Ag2CO3 nanorods (NRs) was evidenced using degradation of organic dye methylene blue as a test reaction. Also, the formation of composites improved their stability under long run illumination conditions. The effect of AgX content on photocatalytic activity of the composites were also investigated. The possible photocatalytic mechanism that facilitates efficient separation of photo-formed charge carriers in heterostructures was discussed in terms of the relative energetic of valence and conduction bands.

AB  - The synthetic procedures for preparation of free-standing and attached to polymer support surface modified TiO2 nanoparticles (NPs) with absorption extended into the visible spectral region due to charge transfer complex formation were developed. The one-step synthesis of colloids consisting of surface-modified TiO2 NPs is based on the reaction between titanium(IV) isopropoxide (TTIP) and lauryl galatte in nonprotic organic solvents (tetrahydrofuran, xylol, chloroform). The poly(GMA-co-EGDMA) copolymer decorated with surface-modified TiO2 NPs was obtained in two steps. First, copolymer was functionalized with dopamine and then treated with TTIP in organic solvent at slightly elevated temperature. Thorough microstructural and optical characterization of free-standing and attached to polymer support surface-modified TiO2 NPs was performed involving transmission electron microscopy as well as absorption and reflection spectroscopy. Infrared spectroscopy was used to understand coordination of ligands to surface Ti atoms. Photoredox chemistry of surface-modified TiO2 NPs attached to the polymer support was tested. Enhanced photooxidative ability of composite was demonstrated by degradation of organic dye crystal violet under visible light illumination, i.e., using photons with energy smaller than 2.75 eV. On the other hand, photocatalytic hydrogen production was used to demonstrate photoreduction ability of surface modified TiO2 NPs attached to the polymer support.

AB  - TiO2 powders with different specific surface area were prepared using reproducible, sol gel synthetic route and their ability to form hybrids with catechol and 5-amino salicylic acid was compared with the commercially available Degussa P25 TiO2 powder. Microstructural characterization involving transmission electron microscopy, X-ray diffraction analysis and nitrogen adsorption-desorption isotherms indicated that TiO2 samples cover reasonably wide size and/or specific surface area range (50-115 m(2)/g). The surface modification of TiO2 powders with catechol and 5-amino salicylic acid induced significant shift of absorption to the visible spectral region due to charge transfer complex formation. It should be emphasized that tunable optical properties of TiO2 in powder form have never been reported in the literature. The largest red shift of the absorption onset was observed for sample with the largest specific surface area upon surface modification with both ligands.

AB  - Nanocomposites (NCs) with different content of silver nanoparticles (Ag NPs) embeded in polystyrene (PS) matrix were prepared by in situ bulk radical polymerization. The nearly monodisperse Ag NPs protected with oleylamine were synthesized via organic solvo-thermal method and further used as a filler. The as-prepared spherical Ag NPs with diameter of 7.0 +/- 1.5 nm were well dispersed in the PS matrix. The structural properties of the resulting Ag/PS NCs were characterized by transmission electron microscope (TEM) and Fourier transform infrared (FTIR) spectroscopy, while optical properties were characterized using optical absorption measurements. The gel permeation chromatography (GPC) measurements showed that the presence of Ag NPs stabilized with oleylamine has no influence on the molecular weight and polydispersity of the PS matrix. The influence of silver content on the thermal properties of Ag/PS NCs was investigated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results indicated that resistance of PS to thermal degradation was improved upon incorporation of Ag NPs. The Ag/PS NCs have lower glass transition temperatures than net PS because loosely packed oleylamine molecules at the interface caused the increase of free volume and chain segments mobility near the surface of Ag NPs.

AB  - Homogeneous and crack-free TiO2 films with templated mesoporosity were prepared by the dip coating technique using an evaporation-induced, self-assembly method. The synthesized mesoporous TiO2 films were characterized using SEM/TEM, BET and XRD techniques. Degradation reactions of methylene blue and crystal violet dyes were used to test the photocatalytic capability of mesoporous TiO2 films. The degradation kinetics of methylene blue and crystal violet were investigated over a broad range of initial concentrations of the organic dyes. The kinetic data were correlated with the specific surface area and thickness of mesoporous TiO2 films, as well as number of reaction cycles.

AB  - Prismatic and plate-like silver nanoparticles (Ag NPs) were synthesized according to the seed-mediated method. These particles were used as precursors for preparation of homogenous, transparent and colored Ag/poly(vinyl alcohol) (PVA) nanocomposite films with different concentrations of Ag by solution-casting technique. Optical and structural characterization of these nanocomposites includes UV-visible spectroscopy, X-ray diffraction (XRD), FTIR spectroscopy and SEM measurements. Further, the effect of embedded nanoparticles on the thermal properties of the PVA matrix was studied. The value of the glass transition temperature of polymer is found to increase after embedding Ag NPs. Comparison of thermal properties of pure PVA and nanocomposite films showed that the thermo-oxidative stability of polymer slightly increased in the presence of Ag NPs. Furthermore, the effect of the Ag NPs on the crystallinity of polymer was also observed.

AB  - Incorporation of surface modified TiO2 nanoparticles into polystyrene (PS) matrix was achieved by in situ bulk radical polymerization of styrene. The surface of TiO2 nanoparticles was modified with four amphiphilic esters of the gallic acid (octyl, decyl, lauryl and cetyl gallate), which have different lengths of hydrophobic alkyl chain (C8C16). FTIR and UV-Vis spectroscopy measurements confirmed the formation of a charge transfer complex between surface Ti atoms and gallic esters. Microstructural characterization of the synthesized nanocomposites revealed that the best dispersion of TiO2 nanoparticles in PS was achieved when the TiO2 surface was modified with octyl gallate. The presence of surface modified TiO2 nanoparticles by different alkyl gallates does not have an influence on the molecular weight and glass transition temperature of PS matrix. On the other hand, thermal and thermo-oxidative stability of PS were significantly improved by incorporation of surface modified TiO2 nanoparticles. The most pronounced improvement of thermal and thermo-oxidative stability was observed for TiO2 nanoparticles surface modified with octyl gallate. POLYM. COMPOS., 2013.

AB  - Nanocomposites (NCs) with different amount of silver nanoparticles (Ag NPs) embedded
in polystyrene (PS) matrix were prepared by in situ radical polymerization. In order to
achieve homogeneous distribution of Ag NPs in the PS matrix, the nearly monodisperse Ag
NPs (7.0 ± 1.5 nm) protected with oleylamine were first synthesized via organic solvothermal
method and further used as a filler. For this purpose, a simple colloidal method
for preparation of Ag NPs in organic solvent was developed. PS was selected as the
polymer matrix based on its optical transparency and high chemical resistance. The gel
permeation chromatography (GPC) measurements showed that the presence of Ag NPs
stabilized with oleylamine during the polymerization of styrene have no influence on the
molecular weight and polydispersity of the PS matrix. The structural properties of the
resulting Ag/PS NCs were characterized by transmission electron microscope and FTIR
spectroscopy. The influence of the presence of Ag NPs and their concentration on the
optical properties of PS matrix was investigated in details using UV-Vis spectroscopy. Since
the PS represents a nonabsorbing medium throughout the visible spectrum, the
improvement of the optical performances of polymer was achieved by incorporation of
the appropriate size Ag NPs with strong plasma resonance absorption.

abstract = "Nanocomposites (NCs) with different amount of silver nanoparticles (Ag NPs) embedded
in polystyrene (PS) matrix were prepared by in situ radical polymerization. In order to
achieve homogeneous distribution of Ag NPs in the PS matrix, the nearly monodisperse Ag
NPs (7.0 ± 1.5 nm) protected with oleylamine were first synthesized via organic solvothermal
method and further used as a filler. For this purpose, a simple colloidal method
for preparation of Ag NPs in organic solvent was developed. PS was selected as the
polymer matrix based on its optical transparency and high chemical resistance. The gel
permeation chromatography (GPC) measurements showed that the presence of Ag NPs
