摘要
Abstract Using solar energy to convert CO 2 into valuable fuels or chemicals offers a powerful solution to urgent energy and environmental problems. However, the development of efficient and selective catalysts remains a considerable scientific challenge. To address this, catalytically active Co II centers can be anchored into the porous matrix of metal–organic frameworks (MOFs) by utilizing a robust Zr‐based MOF (Zr‐DMBD) functionalized with freestanding thiol groups to enable efficient post‐synthetic metal insertion. The thus‐prepared Zr‐DMBD−Co MOF solids are modified by well‐defined Co–thiolate units and have the capability of photocatalytically converting CO 2 into CO with high efficiency and selectivity under visible‐light irradiation in a water‐containing system. The turnover number and CO selectivity reach as high as 97 941 and 98 %, respectively.
