Summary: A hydrogenated black m-TiO2/CeO2 nanocomposite aerogel was prepared and showed enhanced photocatalytic activity in degrading Rhodamine B and water splitting under visible-light irradiation. The photocatalytic enhancement mechanisms included large specific surface area, enhanced conductivity, and the generation of self doped defects in the Z-scheme heterojunction, providing more active sites, extending the absorption range of solar light, and suppressing carrier recombination.

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: MoS2/TiO2 composite photocatalysts with visible-light activity were successfully fabricated on titanium substrates via a simple two-step hydrothermal synthesis method. The presence of MoS2 significantly enhances the visible light absorption of the catalyst, leading to a higher photocatalytic oxidation rate of NO2-. The composite exhibited a band gap of about 2.2 eV and good photoactivity, making it a promising material for environmental remediation applications.

Summary: Metal oxide semiconductor, particularly titanium dioxide (TiO2), is widely used in photocatalytic treatment of dye wastewater, but faces challenges such as low sunlight utilization and fast recombination of electron-hole pairs. Through synthesizing muscovite supported TiO2 with tungsten dopant, this study achieved improved separation efficiency of photoinduced carriers and enhanced photocatalytic activity, providing a novel strategy for preparing efficient and stable TiO2-based photocatalytic materials.

Summary: The interest in removing emerging contaminants has increased in the past decade. The study focused on the synthesis, characterization, and photocatalytic evaluation of TiO2-F, CuO/TiO2-F, and NiO/TiO2-F composite materials for degrading caffeine using UV radiation. While the fluorination of titanium dioxide improved the physicochemical properties and photocatalytic performance, incomplete mineralization was observed.

Summary: Membrane filtration and affinity-based adsorption are commonly used separation strategies. Researchers designed multifunctional and sustainable composite membranes with enhanced properties using cellulose acetate and functionalized cellulose nanocrystals. The impregnation of cationic CNCs significantly increased the tensile strength of the membranes, while anionic CNCs improved particle retention efficiency. These membranes can be utilized for selective trapping of bacteria or substances of biological significance.
