The utilization of 2D materials as catalysts has garnered significant attention in recent years, primarily due to their exceptional features including high surface area, abundant exposed active sites, and tunable physicochemical properties. The unique geometry of 2D materials imparts them with versatile active sites for catalysis, including basal plane, interlayer, defect, and edge sites. Among these, edge sites hold particular significance as they not only enable the activation of inert 2D catalysts but also serve as platforms for engineering active sites to achieve enhanced catalytic performance. Here it is comprehensively aimed to summarize the state-of-the-art advancements in the utilization of edge sites on 2D materials for electrocatalysis and photocatalysis, with applications ranging from water splitting, oxygen reduction, and nitrogen reduction to CO reduction. Additionally, various approaches for harnessing and modifying edge sites are summarized and discussed. Here guidelines for the rational engineering of 2D materials for heterogeneous catalysis are provided.
近年来，二维材料作为催化剂的应用受到了广泛关注，这主要归功于其优异的特性，包括高比表面积、丰富的暴露活性位点以及可调控的物理化学性质。二维材料独特的几何结构赋予了它们用于催化的多功能活性位点，包括基面、层间、缺陷和边缘位点。其中，边缘位点尤为重要，因为它们不仅能够激活惰性二维催化剂，还可作为工程活性位点的平台，以实现增强的催化性能。本文全面总结了二维材料边缘位点在电催化和光催化应用方面的最新进展，这些应用涵盖了从水分解、氧还原、氮还原到一氧化碳还原等领域。此外，还总结并讨论了利用和修饰边缘位点的各种方法。本文提供了用于多相催化的二维材料合理工程设计指南。
