Abstract In this study, 2D multimetallic MOFs combined with the advantages of nanosheets, synergetic effect nodes, exhibited good photocatalytic activity for reduction CO 2 . Herein, a MOF‐Co/Cu/Fe were successfully prepared via one‐pot stirring solutions multimetal salts and organic ligands at room temperature. Introduction second third metal (Cu Fe) into MOF‐Co does not change morphology MOFs, although it improved performance by broadening light absorption range MOF‐Co, accelerating separation efficiency transfer rate photogenerated carriers. Upon irradiation full‐spectrum light, average yield achieved 17.06 µmol·g −1 ·h , being about 1.8 1.2 times that MOF‐Co/Cu. This work provides an insight MOFs‐based photocatalysts in catalytic reduction.
