Abstract

Using first-principles methods, we proposed a p–m–n heterojunction as an efficient Z-scheme photocatalyst design with energy-dependent charge delivery, where the opposite band-bending trends at the p–m and m–n interfaces would enable the selective steering of low-energy charges from two semiconductors to the intermediate metal, while keeping the high-energy electrons and holes in the individual semiconductors for driving reduction and oxidation reactions separately.
