Perovskite materials as photocatalysts: Current status and future perspectives

Abstract Since its first discovery in 1839, perovskite materials have received strong research interests and are gaining tremendous developments over the past and recent decades. Nowadays, they are being recognized among the most promising materials in renewable energy sources, energy storage, and pollutant degradation of the 21st century due to their superior catalytic and photoelectric properties. This chapter provides a complete overview of perovskites as photocatalysts, from the fundamental properties, their applications, and a review of the current research status of this material family. The different synthetic methods of the perovskites will be summarized in this chapter. In addition, this chapter will deliver to the readers some most important applications of nanoperovskites in the catalysis field. Particularly, the application and recent development of halide perovskite catalysts in organic synthesis, which is seemed as one of the most special and promising applications for this type of material, is presented in more detail. Emphasis is also given toward the application of density functional theory calculations and machine-learning driven method as the state-of-the-art approach in the study and design of better efficient perovskite catalysts. Finally, the application of the unconventional sonochemical synthesis technique is also briefly introduced, which could open a breakthrough development in the nanoperovskite materials design.
