Research progress of TiO2-based photocatalytic materials

Abstract TiO2 is the most widely studied photocatalyst, which has a good application prospect in the field of environmental pollution control and has always been a hot spot of photocatalytic materials research. The crystalline structure, surface morphology, and optical properties of TiO2-based photocatalytic materials prepared by different methods are different, and thus exhibit different photocatalytic properties. In this paper, the research progress of TiO2-based photocatalytic materials in China and abroad in recent years was reviewed based on the common preparation methods.
