As one of the most attractive technologies, photocatalysis has been emerging nowadays to harvesting the solar energy for producing green fuels and a wide range of environmental applications. Due to their unique physicochemical and optical properties, a wide variety of TiO2 based photocatalysts have emerged to drive various organic transformations and degradation reactions under light irradiation. In this chapter, we have systematically summarized the fundamentals of TiO2 based photocatalysts, including basic mechanism of heterogeneous photocatalysis, advantages, and challenges of g- TiO2 based photocatalysts. Through reviewing the important state-of-the-art advances on this topic, it may provide new opportunities for designing and constructing highly effective TiO2 and various bismuth-based photocatalysts for various applications in photocatalysis and other related fields, such as solar cells and photoelectrocatalysis.
