Abstract
With the characteristics of strong and wide light absorption, long excited state lifetime, high photoluminescence quantum yield, effective separation of photoluminescent carriers and adjustable band width, perovskite materials are potential in the fields of photocatalytic degradation, organic synthesis, hydrogen evolution, and dioxide photoreduction. This review focuses on the photocatalytic organic reactions (degradation, selective oxidation and organic polymerization), conversion process of solar energy to chemical fuels (water splitting and carbon dioxide emission reduction) and the design of electronic, crystal and surface structure of perovskite catalysts, especially for partial ABO3 perovskites (ATiO3 perovskite-type oxides, AFeO3 perovskite-type oxides, niobate calcium titanite perovskites, layered perovskites) and halide perovskites (tin-based halide perovskites, halide oxide perovskites, all-inorganic perovskites). Strategies such as ions doping, construction of different heterostructures, noble metal decoration, morphological engineering (crystal structure and size, crystallinity, and particle structure) are discussed to suppress charge recombination, improve adsorption activity, and enhance photoelectron excitation/transfer and light absorption. Finally, the route for perovskite photocatalysts to implementing the practical application is discussed.
