Summary: Hydrothermal reactions are a simple and efficient method for preparing nanostructured TiO2 particles with large specific surface area for photocatalytic applications. The effects of different synthesis parameters on morphology and photocatalytic activity were studied, showing that the final calcination temperature significantly affects degradation rates. Initial morphology had little effect on photocatalytic properties, with results comparable to P25 TiO2 nanoparticles.

Summary: TiO2/ZnO nanocomposites with different Ti/Zn ratios were successfully synthesized by sol-gel and hydrothermal methods, exhibiting excellent photocatalytic performance. The degradation rate of methylene blue by TiO2/ZnO nanocomposites with a Ti/Zn ratio of 2:1 was close to 100%, outperforming other samples. The improved catalytic performance was attributed to the ability to separate holes and electrons.

Summary: The TiO2/ZnO heterojunction thin films combined with surface oxygen vacancies prepared through magnetron sputtering showed enhanced photocatalytic performance in degrading organic pollutants in water. By controlling the O-2/Ar ratio, the morphology, thickness, chemical composition, and crystal structure of the films can be regulated to improve photocatalytic efficiency. The heterojunction thin film exhibited superior photocatalytic properties due to the heterojunction interface and surface oxygen vacancies, accelerating the separation of electron-hole pairs.

Summary: Heterogeneous photocatalysis is a promising technology for green and sustainable chemical processes. This study investigates the relationship between the structure, properties, and activity of photocatalysts in order to improve their design. The authors propose a simple rate equation that relates the specific surface area (S-BET) and the lifetime of photoexcited carriers (tau) to the photocatalytic activity. Their findings suggest that both S-BET and tau are important factors affecting the activity of photocatalysts.

Summary: This study investigates the photocatalytic degradation of methylene blue using flowerlike rutile-phase TiO2 films synthesized by a hydrothermal method. The research reveals that various parameters such as catalyst morphology, oxygen vacancy/Ti3+ surface defects, pH of the methylene blue solution, and initial concentration of the dye influence the photocatalytic activity of the TiO2 film. The presence of oxygen vacancy/Ti3+ surface defects is found to enhance the photocatalytic activity by acting as an electron trap.
