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  - 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.

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  - 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  - We report the successful, low temperature synthesis of pure and Fe-doped titania nanoparticle (NP) powders, using organic Ti- and Fe-precursors. The properties of the synthesized titania based materials were obtained using XRD, UV/vis and EPR spectroscopy and BET measurements. 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. The photocatalytic activity, using simulated Solar light (Vitalux lamp), of our samples was checked by following the photodegradation reaction of Rhodamine B and trichlorophenole as model compounds.
