Traditional CO2 cycloaddition needs strict conditions, co-catalyst and solvent, causing energy intensive and complex recycle process. In this work, an integrated ionic polymers (IPs) and phosphomolybdate (PM012) co-modified CuTCPPCo MOF all-in-one composite catalyst (PBPCT*) is designed for solar driven, solvent-free and co-catalyst-free CO2 cycloaddition. The PMo_(12) clusters and IPs offer abundant active sites for reactants activation and ring opening. The activation energy significandy decreases from 66.36 kJ·mol~(-1) of CuTCPPCo MOF to 49.47 kJ·mol~(-1) of PBPCT*, and guarantees higher efficient with 99.2% yield of styrene carbonate at 353 K for 12 h. The TOF of 580.73 h~(-1) under light density of 0.8 W/cm~2 superior to traditional heating with TOF of 473.0 h~(-1). This provides a new avenue to gather all the advantages in one catalyst, furnishing a promising approach for reducing CO2 emission and utilization. 收起
