AB  - Nanokompozitni prah ZrO2/Fe3O4 sintetisan je uspešno u nekoliko koraka. Prvo su sintetisane nanočestice magnetita sa zaštitnim slojem od SiO2 koji sprečava prenos elektrona iz provodne zone ZrO2 na magnetit prilikom ozračivanja. Potom je na nanočestice nanet sloj ZrO2 solvotermalnom metodom. Dobijeni prah je prečišćen uz pomoć permanentnog magneta koji obezbeđuje potpuno ukalanjanje magnetnog materijala iz rastvora. Ovako sintetisan magnetni materijal je upotrebljen kao fotokatalizator u reakcijama razgradnje 2,4 dihlorofenolai 2,4,6 trihlorofenola u vodenim rastvorima. Rezultati su pokazali da je nanokompozit efikasan adsorber i fotokatalizator za odabrana jedinjenja. Hlorofenoli su izabrani kao model jedinjenja u ovoj studiji zbog toga što se često nalaze u prirodnim vodama, u koje stižu iz pesticida koji se upotrebljavaju u poljoprivredi. Njihova toksičnost se najviše ogleda u uticaju na nervini sistem životinja i ljudi.
AB  - Nanocomposite powder ZrO2/Fe3O4 was synthesized in several steps. Firstly, magnetite nanoparticles with a protective layer of SiO2 were synthesized. Silica layer protects magnetite core and prevents the transfer of electrons from the conduction band of ZrO2 to magnetite during illumination. Secondly, a layer of ZrO2 was added to the nanoparticles by the solvothermal method. The resulting powder was purified with the help of a strong magnet that ensures complete separation of the magnetic material from the solution. The magnetic material thus synthesized was used as a photocatalyst in the decomposition reactions of 2,4 dichloro- and 2,4,6 trichloro- phenols in aqueous solutions with Simulated Solar light as an irradiation source. The results showed that nanocomposite is an effective adsorber and photocatalyst for selected compounds. Chlorophenols were chosen as a model of compounds in this study because they are often found in natural waters, which come from pesticides used in agriculture. Their toxicity is mostly reflected in the impact on the nervous system of animals and humans.

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  - Various particles and materials, including pollutants, deposited on urban surfaces are washed off by stormwater runoff during rain events. The interactions between the solid and dissolved compounds in stormwater runoff are phenomena of importance for the selection and improvement of optimal stormwater management practices aimed at minimizing pollutant input to receiving waters. The objective of this research was to further investigate the mechanisms responsible for the partitioning of heavy metals (HM) between the solid and liquid phases in urban stormwater runoff. The research involved the collection of samples from urban asphalt surfaces, chemical characterization of the bulk liquid samples, solids separation, particle size distribution fractionation and chemical and physicochemical characterization of the solid phase particles. The results revealed that a negligible fraction of HM was present in the liquid phase (less than 3% by weight), while there was a strong correlation between the total content of heavy metals and total suspended solids. Examinations of surface morphology and mineralogy revealed that the solid phase particles consist predominantly of natural macroporous materials: alpha quartz (80%), magnetite (11.4%) and silicon diphosphate (8.9%). These materials have a low surface area and do not have significant adsorptive capacity. These materials have a low surface area and do not have significant adsorptive capacity. The presence of HM on the surface of solid particles was not confirmed by scanning electron microscopy and energy dispersive X-ray microanalyses. These findings, along with the results of the liquid phase sample characterization, indicate that the partitioning of HM between the liquid and solid phases in the analyzed samples may be attributed to precipitation processes.
