AB  - Urea-based graphitic carbon nitride (g-C3N4) is thermally exfoliated at 500 °C in the airatmosphere, and nano-carbon nitride (n-C3N4) is obtained. While optical properties are assessedusing UV/Vis DR spectroscopy, structural and morphological parameters of two materials areobtained using XRD, TEM, and FTIR. Flat-band potentials were determined from Mott-Schottkyplots, and combined with corresponding band-gap energies, to estimate conduction and valenceband potentials of both materials. Photocatalytic efficacy of both semiconductors in photocatalyticdegradation of three textile dyes under simulated solar light irradiation is compared, with theconclusion that n-C3N4 expressed higher photocatalytic ability in the studied systems. Finally, inorder 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 resultsshowed that this material can have a future in solving real-life environmental problems.

AB  - The mesoporous zirconia/alumina composites were synthesized via a sol–gel method,
followed by heat treatment at 500 ◦C for 5 h. The effect of the ZrO2/Al2O3 ratio on the structural and
textural properties of the obtained composites was explored. Sorption analysis has confirmed that
all samples have a mesoporous structure whose parameters (SBET, Vp and Dmax) strongly depend
on the ZrO2/Al2O3 ratio. The XRD pattern of composites has shown that the addition of zirconia
disrupts the crystallinity of alumina. The composites with higher zirconia content (50% ZrO2 and
67% ZrO2
) are characterized by peaks related only to the zirconia phase. UV/Vis diffuse reflection
spectra of all samples revealed that composites have more intensive absorption compared to pure
oxides for wavelengths larger than 250 nm and similar band gaps. Photoluminescence measurements
showed presence of defects in all samples, which are responsible for photocatalytic activity. All
samples showed significant adsorption/photocatalytic efficacy for the removal/degradation of 2,4,6
-trichlorophenol (TCP). Results obtained using HPLC and TOC techniques showed that between 70
and 80% of the initial TCP concentration was removed/degraded after 4 h of illumination. These
results were corelated with flat, conduction and valence band potentials of synthesized pure and
binary oxides, calculated using Mott–Schottky plots.

AB  - 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.
