Since Fujishima and Honda first reported in 1972 the photoelectrochemical water splitting of water through TiO2 under UV light irradiation, photocatalysis has attracted a growing amount of research attention. Various types of materials with photocatalytic properties such as metal oxides, metal sulfides, polymers, MOFs etc have been reported for solar energy conversion, storage and utilization, through redution and/or oxidation reactions generating added value products including hydrogen, oxygen and hydrocarbons. Recently, metal halide perovskites(MHPs) have found tremendous popularity in solar to electricity conversion due to the high extinction coefficients, the wide absorption range and long electron−hole diffusion lengths of these materials. All of the mentioned MHP properties match well with the necessary conditions set forward for photocatalytic materials making them potentially interesting photocatalyst, a main concern is however related to their (chemical) stability under reaction conditions.
