Photoreduction of CO into sustainable and green solar fuels is generally believed to be an appealing solution to simultaneously overcome both environmental problems and energy crisis. The low selectivity of challenging multi-electron CO photoreduction reactions makes it one of the holy grails in heterogeneous photocatalysis. This Review highlights the important roles of cocatalysts in selective photocatalytic CO reduction into solar fuels using semiconductor catalysts. A special emphasis in this review is placed on the key role, design considerations and modification strategies of cocatalysts for CO photoreduction. Various cocatalysts, such as the biomimetic, metal-based, metal-free, and multifunctional ones, and their selectivity for CO photoreduction are summarized and discussed, along with the recent advances in this area. This Review provides useful information for the design of highly selective cocatalysts for photo(electro)reduction and electroreduction of CO and complements the existing reviews on various semiconductor photocatalysts.
将 CO 光还原为可持续和绿色的太阳能燃料通常被认为是一种有吸引力的解决方案，可以同时克服环境问题和能源危机。具有挑战性的多电子 CO 光还原反应的低选择性使其成为多相光催化中的圣杯之一。本综述强调了助催化剂在使用半导体催化剂选择性光催化 CO 还原为太阳能燃料中的重要作用。本综述特别强调了助催化剂在 CO 光还原中的关键作用、设计考虑因素和改性策略。总结并讨论了各种助催化剂，如仿生、基于金属、无金属和多功能助催化剂，以及它们对 CO 光还原的选择性，以及该领域的最新进展。本综述为设计用于光（电）还原和 CO 电还原的高选择性助催化剂提供了有用的信息，并补充了各种半导体光催化剂的现有综述。
