Solar-driven carbonylation with CO2 replacing toxic CO as a C1 source is of considerable interest; however it remains great challenge due to the inert molecule. Herein, we integrate cobalt single-site and ultrafine CuPd nanocluster catalysts into porphyrin-based metal-organic framework construct composite photocatalysts (Cu1Pd2)z@PCN-222(Co) (z = 1.3, 2.0, 3.0 nm). Upon visible light irradiation, excited porphyrin can concurrently transfer electrons Co single sites nanoclusters, providing possibility for coupling photoreduction Suzuki/Sonogashira reactions. This multicomponent synergy in (Cu1Pd2)1.3@PCN-222(Co) not only replace dangerous gas but also dramatically promote photosynthesis benzophenone over 90% yield 97% selectivity under mild condition. Systematic investigations clearly decipher function collaboration among different components these catalysts, highlighting new insight developing sustainable protocol reactions by employing greenhouse source.
