Metal synergy can enhance the catalytic performance, and a prefabricated solid precursor guide ordered embedding, of secondary metal source ions for rapid synthesis bimetallic organic frameworks (MM'-MOFs) with stoichiometric ratio 1:1. In this paper, Co-MOF-1D containing well-defined binding sites was synthesized by mechanical ball milling, which used as template induced introduction Fe to successfully assemble Co1Fe1-MOF-74@2 (where @2 denotes template-directed MOF-74). Its electrocatalytic performance is superior that conventional one-step-synthesized Co1Fe1-MOF-74@1 @1 one-step MOF-74), two sources, Co Fe, close Meanwhile, iron valence states (FeII FeIII) in were further regulated obtain materials Co1Fe1(II)-MOF-74@2 Co1Fe1(III)-MOF-74@2. The electrochemical test results confirm state has better than Co1Fe1(III)-MOF-74@2 oxygen evolution reaction (OER) process. This phenomenon related gradual increase Co1Fe1(II)-MOF-74@2, promotes continuous improvement MOF before reaching optimal steady makes OER reach optimum when FeII/FeIII mixed-valence reaches certain proportion. provides new idea directed optimization highly efficient catalysts.
