Abstract

We present enhanced electrocatalytic activity of three-dimensional graphene scaffolds by decoration with one-dimensional Co_xNi_1-x MOF nanostructures (0 ≤x≤ 1). The decreased overpotential and fast kinetics of the oxygen evolution reaction as compared with the existing materials are shown. The developed bimetallic MOF/3DG composites have great potential to be used in electrocatalytic water oxidation.
