Dinuclear metal synergistic catalysis(DMSC)has been proved powerful in boosting CO_(2)reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework(MOF),obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center(M-In),three MOFs with dinuclear homometallic catalytic centers(MM-In),and three MOFs with dinuclear heterometallic catalytic centers(MM’-In,M/M’=Co(II),Ni(II),Zn(II)).It was found that all these MOFs can serve as catalysts for photochemical CO_(2)reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g^(-1)h^(-1),which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO_(2)reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO_(2)reduction.
