 摘要：To enhance the economic viability of photocatalytic materials for carbon capture and conversion, the challenge of employing expensive photosensitizer must be overcome. This study aims to improve the visible light utilization with zirconium-based metal-organic frameworks (Zr-MOFs) by employing a multi-component post-synthetic modification (PSM) strategy. An economical photosensitiser and copper ions are introduced into MOF 808 to enhance its photoreduction properties. Notably, the PSM of MOF 808 shows the highest CO yield up to 236.5 μmol g^-1h^-1 with a HCOOH production of 993.6 μmol g^-1h^-1 under non-noble metal, and its mechanistic insight for CO₂ reaction is discussed in detail. The research results have important reference value for the potential application of photocatalytic metal-organic frameworks.
