Semiconductor heterogeneous photocatalysis is currently utilized within a wide variety of societally impactful processes, spanning reactions such as hydrogen production and CO2 conversion, to the organic transformation of raw materials for value-added chemicals. Metal halide perovskites (MHPs) have recently emerged as a new promising class of cheap and easy to make photocatalytic semiconductors, though their unstable ionically bound crystal structure has thus far restricted widespread application. Recently years, we examine the issues hampering MHP-based photocatalysis and proposal a general approach being taken to achieve promising and stable photocatalytic reaction environments. Specifically, we utilize relatively low-polarity solvents such toluene and trifluorotoluene for CO2 photoreduction and organic transformations over MHPs. However, the effectiveness of single MHP photocatalysts is relatively poor. We further introduction of a second component to form a heterojunction, including Schottky, type II, and Z-scheme heterojunction, to accelerate carrier migration and boost reaction rates, thus increasing the photoactivity. © FUNDACIO DE LA COMUNITAT VALENCIANA SCITOnanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009.
