Summary: In this study, MWCNT-WO3 nanocomposites were successfully prepared and tested for their photocatalytic degradation performance on synthetic MB dye under UV activation. TEM and SEM observations confirmed the attachment of WO3 nanoparticles on MWCNT surface, with improved thermal stability of the composites as WO3 content increased. Photocatalytic experiments demonstrated that the addition of MWCNTs significantly enhanced the degradation efficiency of WO3, particularly shown in the high efficiency of the optimum MWCNT-W-7 composite.

Summary: High quality silver (Ag) decorated CeO2 nanoparticles were prepared by a facile one-step chemical method and used as a catalyst for degrading harmful textile pollutant Rose Bengal dye under sunlight with a high efficiency of 96% degradation rate after 3 hours. The enhancement in degradation efficiency was mainly attributed to the decrease in band gap and charge carrier recombination rate, with a possible degradation mechanism proposed based on the generation of oxygen vacancies due to the decoration of Ag on the CeO2 surface.

Summary: A new method for photocatalytic sterilization and degradation was studied using sea urchin-like WO3-x and Ag nanoparticles (Ag NPs) supported on WO3-x nanospheres to prepare Ag/WO3-x composites. The experimental results showed that Ag/WO3-x composites exhibited higher photocatalytic degradation and bactericidal effects, which may be attributed to the enhanced photocatalytic performance of the composites after WO3-x loaded with Ag NPs.

Summary: In this study, tungsten-doped titania nanotubes were synthesized to enhance their reactivity in the photodegradation of various dyes under UV radiation. The W-doped TNs exhibited a high specific surface area and the presence of W6+ species, as confirmed by XPS spectra. The photodegradation of the dyes involved two-step reactions, and the W-doped TNs showed optimal photocatalytic efficiencies for the degradation of each dye.

Summary: A nanocomposite photocatalyst consisting of MgAl2O4 spinel and WO3 powders was synthesized through grinding. Characterization using various techniques revealed the presence of WO3 and MgAl2O4 in the nanocomposite. The nanocomposite showed a shift in absorption edge and a decrease in optical band gap energy compared to pure WO3. The nanocomposite also exhibited higher photocatalytic degradation efficiency for methylene blue, with the most complete degradation achieved using a 20%WO3/MgAl2O4 nanocomposite.
