| Summary: | Photoredox catalysis, which can legitimately change visible-light (solar energy) into chemical energy, is a swiftly rising and promising approach to instigate chemical reactions because solar energy is clean, inexpensive, boundless and simply available energy resource. For many important organic transformations, photocatalytic alternates such as transition-metal-based photocatalysts, organic dyes and many nanoparticles have been reported to catalyze photocatalytic organic reactions through electron–hole transfer process. Recently, immense efforts and encouraging achievements are accomplished in the area of semiconductor perovskite-type catalytic materials as a photocatalysts in organic synthesis, owing to their ‘structural adjustability and fascinating convenient physicochemical properties’. Hitherto, unique photo-catalytic properties of several perovskite-type catalytic materials as substitutes of noble metals have been advanced and their functions in photoredox catalysis examined. From the beginning of 2017, the research on photoredox catalysis using perovskite as a photocatalyst has meant one of the innovative pattern in heterogeneous photocatalytic organic reactions and is as yet growing. This review covers brand-new accomplishments in soler-driven chemical reactions, for example, C–H activation, redox reaction, bond forming process, coupling reactions, bond cleavage, dehydrogenation, and ring–opening reactions using perovskite-type catalytic materials as a heterogeneous photocatalysts have been reported during last five years.
