Heterogeneous catalysts have been widely used for photocatalysis, which is a highly important process for energy conversion, owing to their merits such as easy separation of catalysts from the reaction products and applicability to continuous chemical industry and recyclability. Yet, homogenous photocatalysis receives tremendous attention as it can offer a higher activity and selectivity with atomically dispersed catalytic sites and tunable light absorption. For this reason, there is a major trend to combine the advantages of both homogeneous and heterogeneous photocatalysts, in which coordination chemistry plays a role as the bridge. In this article, we aim to provide the first systematic review to give a clear picture of the recent progress from taking advantage of coordination chemistry. We specifically summarize the role of coordination chemistry as a versatile tool to engineer catalytically active sites, tune light harvesting and maneuver charge kinetics in heterogeneous photocatalysis. We then elaborate on the common fundamentals behind various materials systems, together with key spectroscopic characterization techniques and remaining challenges in this field. The typical applications of coordination chemistry in heterogeneous photocatalysis, including proton reduction, water oxidation, carbon dioxide reduction and organic reactions, are highlighted.
均相催化剂在光催化中得到了广泛的应用，由于其易于从反应产物中分离催化剂、适用于连续化工和可回收等优点，因此对于能量转换是一个非常重要的过程。然而，均相光催化受到了极大的关注，因为它可以提供更高的活性和选择性，具有原子分散的催化位点和可调谐的光吸收。出于这个原因，将均相和多相光催化剂的优点结合起来是一个主要的趋势，其中配位化学起着桥梁的作用。在本文中，我们旨在提供第一个系统的综述，以清楚地展示利用配位化学的最新进展。我们特别总结了配位化学作为一种通用工具在多相光催化中构建催化活性位点、调节光捕获和操纵电荷动力学的作用。然后，我们详细阐述了不同材料体系背后的共同基本原理，以及该领域的关键光谱表征技术和剩余挑战。还强调了配位化学在多相光催化中的典型应用，包括质子还原、水氧化、二氧化碳还原和有机反应。
