S-scheme photocatalysisA mechanism for charge transfer in photocatalysis where electrons and holes recombine at the interface of two semiconductors with appropriate band alignments, resulting in the accumulation of electrons in the conduction band of one semiconductor and holes in the valence band of the other, thereby preserving redox ability. / 一种光催化电荷转移机制，其中电子和空穴在具有适当能带排列的两种半导体界面处复合，导致电子在一个半导体的导带中积累，空穴在另一个半导体的价带中积累，从而保持氧化还原能力。
