Synergistic effect of nanosheet-array-like NiFe-LDH and reduced graphene oxide modified Ni foam for greatly enhanced oxygen evolution reaction and hydrogen evolution reaction

We have prepared highly efficient bifunctional electrocatalytic composites, Ni x Fe 1 -LDH/rGO/NF ( x = 3, 2, 1), with vertically staggered NiFe-LDH nanosheets grown on Ni foam uniformly modified with reduced graphene oxide through hydrothermal method.
