Present situation and progress of perovskite photocatalytic materials

Photocatalytic technology and photo-Fenton technology are effective means to solve the problems of environmental pollution and energy shortage, and photocatalyst is the research core. Due to its potential in photocatalytic energy conversion and environmental purification, perovskites have become a research hotspot of new photocatalytic materials. In this paper, the characteristics of perovskites, the influencing factors of activity and the development status of them were reviewed. The application progress of perovskite-type photocatalysts in dye wastewater treatment, ammonia nitrogen wastewater treatment, metal ion redox, atmospheric pollutant purification and soil organic matter and heavy metal removal were summarized. The challenges and future development directions in practical application were discussed. Finally, it is pointed out that the key problems in the current development of perovskite photocatalysts are the development of energy-saving green preparation methods, the development of new composite perovskite-type photocatalysts, especially high specific surface area perovskite matrix materials, and the construction of reactors for the characteristics of perovskite-type photocatalysts.
