Research progress in the preparation, modification and application of ABO₃ type perovskite photocatalyst

Since the 21^st century, with the rapid development of industry, the environment is increasingly deteriorating and energy is increasingly scarce. Solar energy is a new type of green energy with great development potential. Photocatalytic technology has attracted extensive attention as one of the most important ways to utilize solar energy. In this paper, the structure, preparation, modification methods and application progress of ABO₃ type perovskite photocatalyst are reviewed, which provides direction for the development of new ABO₃ type perovskite photocatalyst.
