| 利用太阳能将二氧化碳还原为高附加值燃料是当前双碳背景下解决能源和环境问题的有效方案. 金属配合物分子催化剂作为一种均相催化剂, 具有明确的活性位点、高反应活性以及可调的化学结构等特点, 非常有利于提高催化性能和研究催化机理, 在二氧化碳还原反应中已得到广泛应用. 然而, 分子催化剂稳定性不高且难以回收利用, 不利于催化反应的工业化应用. 采用固定化策略构筑分子催化剂/载体的异相化体系在一定程度上解决了这一难题. 我们综述了以多联吡啶类有机物(主要为二联吡啶、三联吡啶、四联吡啶)为配体的钴分子催化剂, 通过共价键合、非共价键合以及构筑有序聚合物等途径异相化在光催化还原二氧化碳方面的研究进展, 最后对分子催化剂异相化的体系在该领域发展面临的挑战进行了总结. |

| The use of solar energy to reduce carbon dioxide (CO2) into high value-added fuels is an effective strategy to address energy and environmental issues under the current background of carbon peaking and carbon neutrality goals. Molecular metal complex catalysts, as homogeneous catalysts, have been widely used in CO2 reduction because they are very beneficial for improving catalytic performance and mechanism studies for their clear active sites, high reactivity and adjustable chemical structures. However, molecular catalysts have low stability and are difficult to recycle, which is also unfavorable for catalytic reactions and industrial applications. This problem has been partially solved by immobilization strategies to construct hybrid systems for molecular catalysts/support. This article reviews the research progress of the heterogenization of cobalt molecular catalysts bearing organic polypyridine compounds (mainly bipyridine, terpyridine, and quaterpyridine) as ligands in photocatalytic reduction of carbon dioxide through covalent bonding, non-covalent bonding, and construction of ordered polymers. Finally, the challenges in the development of heterogenization of molecular catalyst in this field are summarized. |
