AB  - Urea-based graphitic carbon nitride (g-C3N4) is thermally exfoliated at 500 °C in the air
atmosphere, and nano-carbon nitride (n-C3N4) is obtained. While optical properties are assessed
using UV/Vis DR spectroscopy, structural and morphological parameters of two materials are
obtained using XRD, TEM, and FTIR. Flat-band potentials were determined from Mott-Schottky
plots, and combined with corresponding band-gap energies, to estimate conduction and valence
band potentials of both materials. Photocatalytic efficacy of both semiconductors in photocatalytic
degradation of three textile dyes under simulated solar light irradiation is compared, with the
conclusion that n-C3N4 expressed higher photocatalytic ability in the studied systems. Finally, in
order to provide reusability of the semiconductors in multiple consecutive photocatalytic cycles,
both photocatalysts were drop-coated on the jute-based post industrial waste. Reusability of juten-C3N4 material is probed in three consecutive photocatalytic cycles, and the obtained results
showed that this material can have a future in solving real-life environmental problems.

AB  - Coupled oxide ceramic materials possess attractive properties, such as high surface areas, tunable pore size and shapes, various crystal structures, and a multitude of compositions, which endow them with potential applications in various areas of science and technology. Among these, porous zirconia-based ceramic materials, which can be considered as semiconductors with high band gap energy of ~5eV, have been the subject of intense research because of the potential new extensive use in photocatalytical degradation of organic pollutants. In the scope of this study mesoporous coupled alumina/zirconia composites were synthesized via the sol-gel method, followed by heat treatment at 500°C, for 5h. The XRD pattern of composites has shown that the addition of zirconia disrupts the crystallinity of alumina. The composites with higher zirconia content are characterized by peaks of the tetragonal zirconia phase. On the basis of the calculated flat band potentials from Mott-Schottky plots and optical band gaps, the conduction and valence band potentials were estimated for the composite semiconductors. Photocatalytic activity of synthesized samples in the process of degradation of trichlorophenol was obtained and correlated with band potentials and optical properties.

AB  - This work presents the investigation of electrochemical properties of three alumina samples with different structure and crystal water content. The samples were characterized by XRD and FTIR-ATR analysis, confirming the presence of trihydrate, monohydrate and anhydrous alumina. The samples were used as modifiers of carbon paste electrodes. Their electrochemical behavior toward ferricyanide/ferrocyanide redox probe was evaluated by electrochemical impedance spectroscopy and cyclic voltammetry. The electrochemical behavior toward ruthenium hexamine redox probe was investigated by cyclic voltammetry. The response toward quinone/hydroquinone redox probe was evaluated in buffered and unbuffered solution by cyclic voltammetry. It was found that the surface chemistry of investigated samples influenced their electrochemical properties.

AB  - Alumina powders, pure and doped with nickel, were synthetized by sol-gel method and calcined at 500, 900 and 1100oC in order to obtain mesoporous structures with a high specific surface area, well adapTab. to catalytic application. The characterization of samples was performed by XRD, EPR spectroscopy and electrochemical impedance spectroscopy (EIS). XRD analysis showed that the addition of Ni2+, as well as the annealing temperature, affects the structural properties of the obtained composites. EPR analysis revealed the traces of Fe3+ impurities, the presence of oxy defects in alumina and Ni2+ in tetrahedral position for samples calcined at 1100oC. The impedance of the Nafion/alumina modified GCE depended on combined effect of porous structure and surface properties of alumina samples. The electrochemical behavior of a glassy carbon electrode modified with Ni (II)-doped aluminas was studied in 0.5 M NaOH solution, with and without methanol. The electrochemical activity of nickel-doped alumina composites was dictated by the amount of present NiO impurity.

AB  - Series of alkylammonium modified smectites with different alkylammoinum/clay ratios was synthesized (H series). The obtained organoclays were used as precursors for carbon-clay composite materials (C series). Both set of materials were characterized by X-ray diffraction (XRD), point of zero charge (pHPZC), N2 adsorption-desorption isotherms, Raman spectroscopy and electron paramagnetic resonance (EPR) analysis. XRD analysis of organomodified clays confirmed incorporation of HDTMA+ into interlamellar space of smectite. Series of carbonized clays showed constant d001 value of 1.4 nm. The pHPZC of two series differed indicating that carbonization changed the profile of pH dependent sites on the clay surface. Textural properties of the H series decreased throughout the series, while in the C series the most developed porous structure was obtained for sample where HDTMA+ loading was equal to cation exchange capacity. Raman spectroscopy showed that amorphous carbon was formed during carbonization process. The obtained materials were used as modifiers of carbon paste electrode and investigated using electrochemical impedance spectroscopy, cyclic voltammetry and square wave voltammetry. The comparison of electrochemical behavior of H series and C series showed the importance of interlamellar species for charge transfer process. The investigation of influence of composition of carbon paste and form of added carbon showed that performance of carbon-clay based electrodes depended on synergy of different factors. © 2018 Elsevier Ltd
