Crystal Facet‐Engineering of Metal Halide Perovskite Photocatalysts: Progress and Perspectives
Metal halide perovskites (MHPs) have emerged as promising photocatalysts owing to their exceptional optoelectronic properties, yet suffer from rapid charge recombination, sluggish surface kinetics, and instability. Facet engineering, the controlled exposure of specific crystallographic planes, offers an atomic‐leve...
