The photocatalytic reduction of CO into valuable chemicals and fuels has become a significant research focus in recent years due to its environmental sustainability and energy efficiency. Metal halide perovskites (MHPs), renowned for their remarkable optoelectronic properties and tunable structures, are regarded as promising photocatalysts. Yet, their practical uses are constrained by inherent instability, severe electron-hole recombination, and a scarcity of active sites, prompting substantial research efforts to optimize MHP-based photocatalysts. This review summarizes the latest advancements in MHP-based photocatalysis. First the fundamental principles of photocatalysis are outlined and the structural and optical characteristics of MHPs are evaluated. Then key strategies for enhancing MHP photocatalysts, including morphology and surface modification, encapsulation, metal cation doping, heterojunction engineering, and molecular immobilization are highlighted. Finally, considering recent research progress and the needs for industrial application, challenges and future prospects are explored. This review aims to support researchers in the development of more efficient and stable MHP-based photocatalysts.
近年来，由于光催化将CO还原为有价值的化学品和燃料具有环境可持续性和能源效率，已成为一个重要的研究重点。金属卤化物钙钛矿（MHP）以其卓越的光电性能和可调控结构而闻名，被视为有前景的光催化剂。然而，它们的实际应用受到固有不稳定性、严重的电子-空穴复合以及活性位点稀缺的限制，这促使人们进行大量研究以优化基于MHP的光催化剂。本综述总结了基于MHP的光催化的最新进展。首先概述了光催化的基本原理，并评估了MHP的结构和光学特性。然后重点介绍了增强MHP光催化剂的关键策略，包括形貌和表面改性、封装、金属阳离子掺杂、异质结工程和分子固定。最后，结合近期的研究进展和工业应用需求，探讨了挑战和未来前景。本综述旨在支持研究人员开发更高效、稳定的基于MHP的光催化剂。
