Electronic structure engineering on Co-based metal–organic frameworks for concurrent electrocatalytic hydrogen generation and formate electrosynthesis

Abstract

A facile one-step solvothermal method was developed to synthesize Ir-doped Co-based metal–organic framework (CoIr-MOF) nanoarrays as a bifunctional electrocatalyst for water–glucose co-electrolysis. It was demonstrated that in situ incorporation of a low-content of Ir cations could modulate the electronic structure of Co active centers and thus boost the electrocatalytic performance towards both the hydrogen evolution reaction and glucose-to-formate oxidation reaction.
