Abstract
- The photocatalytic reduction of carbon dioxide into high value-added chemical feedstock is significant for mitigation of the energy crisis and the greenhouse effect. Metal–organic frameworks (MOFs) possess broad application prospects in photocatalytic CO<subscript>2</subscript> conversion due to the ability to adjust the metal types in metal cluster nodes. Herein, the CO<subscript>2</subscript> photocatalytic performance of trimetallic Fe<subscript>0.02</subscript>Ni<subscript>0.10</subscript>–Co<subscript>x</subscript>–PCN-250 (x = 0.05, 0.10, 0.15, 0.20 mol) was investigated by adjusting the content of Co. Notably, the photocatalytic yields of Fe<subscript>0.02</subscript>Ni<subscript>0.10</subscript>–Co<subscript>x</subscript>–PCN-250 (x = 0.05, 0.10, 0.15, 0.20 mol) were higher than those of bimetallic Fe<subscript>0.02</subscript>Ni<subscript>0.10</subscript>–PCN-250 and Fe<subscript>0.02</subscript>Co<subscript>0.10</subscript>–PCN-250 irradiated by visible light. The optimum yield of CO was obtained by trimetallic Fe<subscript>0.02</subscript>Ni<subscript>0.10</subscript>–Co<subscript>0.15</subscript>–PCN-250, up to 299 μmol g<superscript>−1</superscript> h<superscript>−1</superscript>. The enhanced yield of CO might be ascribed to the high CO<subscript>2</subscript> adsorption capacity and photogenerated electron transfer after addition of a suitable amount of the third ion, Co. This study provides new insights by designing trimetallic catalysts to increase the efficiency of photocatalytic CO<subscript>2</subscript> reduction. [ABSTRACT FROM AUTHOR]
