Summary: The use of TiO2 nanoparticles for photocatalysis for the degradation of organic dyes under UV light for wastewater treatment has been widely studied. However, the photocatalytic characteristics of TiO2 nanoparticles are inadequate. In this study, three types of nanoparticles (TiO2, ZrO2, and mixed-phase TiO2-ZrO2) were synthesized and their properties were examined. The results showed that the mixed-phase TiO2-ZrO2 nanoparticles exhibited higher photocatalytic activity for the degradation of Eosin Yellow under visible light compared to TiO2 and ZrO2 nanoparticles.

Summary: Zirconium dioxide-incorporated bismuth sulfide (Bi2S3/ZrO2) and bismuth tungstate (Bi2WO6/ZrO2) heteronanostructures were synthesized and used as photocatalysts for the visible light-driven degradation of chloramphenicol. Both heteronanostructures exhibited excellent catalytic activity, and the degradation rate was greatly enhanced when peroxymonosulfate was used as an activator. The generation and separation of photoinduced charge carriers played a crucial role in the improved catalytic activity. These inorganic heteronanostructures have great potential in the field of contaminated water remediation and provide a platform for the fabrication of photocatalyst materials.

Summary: High surface area, self-organized nanoporous ZrO2 arrays with perfect adhesion to Zr substrate were synthesized by anodization in an aqueous electrolyte. The obtained semiconductor materials were tested as photocatalysts for decolorization of methyl red. The photocatalytic efficiency could be improved by annealing at a relatively low temperature of 350 degrees C, but higher annealing temperatures caused a gradual drop in activity.

Summary: The structural, optical, and mechanical properties of magnetron sputtered TiO2 and TiO2-ZrO2 mixture transparent thin films were investigated, along with the influence of heat treatment. XPS, GI-XRD, and SEM were used to study the structural properties of the films, while spectrophotometry and spectroscopic ellipsometry were employed for optical characterizations. Nano-indentation and nano-scratch tests were used to examine the hardness and scratch behavior. The presence of ZrO2 in TiO2-ZrO2 films enhanced hardness and prevented crystallization of TiO2 after annealing, resulting in better surface quality and higher thermal stability. The addition of ZrO2 also led to a shift in absorption edge and decreased sharpness, leading to less absorption in the visible range.

Summary: The study synthesized ZrO2-doped TiO2 photocatalysts and characterized them using various techniques. It was found that the ZrO2-doped TiO2 exhibited higher photocatalytic activity compared to pure TiO2 and commercial P25. The differences in degradation behavior were attributed to textural properties and structural defects caused by Zr4+ ion doping into the TiO2 lattice.

Summary: By controlling the dosage of triethanolamine, two nanocomposites of monoclinic-ZrO2@rGO and tetragonal-ZrO2@rGO were successfully prepared, with the tetragonal-ZrO2@rGO exhibiting a higher adsorptive amount for OTC. Both nanocomposites show a selective uptake of OTC among tetracycline antibiotics, with adsorption reaching equilibrium in 15 minutes and being independent of pH in the range of 4-8. The interactions between OTC and the nanocomposites were revealed through Fourier transform infrared and XRD analysis, with surface complexation, pi-pi, and cation-pi bonding interactions playing a crucial role.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
