Designing Efficient 2D Photocatalysts through Coordination Activation Mediated Surface Engineering

Abstract

Two‐dimensional (2D) semiconductors with unique structures and surface physicochemical characteristics have been extensively employed for efficient photocatalysis. Recently, surface coordination activation interactions have obtained attention in promoting photocatalytic efficiency as they establish bridges between reactants and photocatalysts. Accordingly, a burgeoning trend in the design of 2D photocatalysts is regulating the surface active centers for coordinating with reactants. These attempts have developed various effective strategies to optimize the 2D photocatalysts and provide in‐depth insights into the structure‐function relationship for heterogeneous photocatalysis. Herein, we summarize recent advances in surface engineering in designing efficient 2D photocatalysts, focusing on coordination activation. We emphasize the advantages of coordination activation as a versatile medium for engineering the surface of photocatalysts. In particular, the discussion includes various strategies for surface engineering and the structure‐function relationship in photocatalysis. This work systematically concludes the significance and future challenges of coordination activation in the surface functionalization of 2D photocatalysis, shedding light on the design of next‐generation photocatalysts.
