We demonstrate that the regulation of metal species in metal-cluster nodes of PCN-250-Fe3 could realize a substantial improvement of conversion activity and selectivity of CO2 reduction. The photocatalysis results revealed that all bi-metallic PCN-250-Fe2M (M = Mn, Zn, Ni, Co) show better catalytic...
