Abstract

Well-ordered NiFe-MOF-74 is in situ grown on Ni foam by the induction of Fe²⁺ and directly used as an OER electrocatalyst. Benefited from the intrinsic open porous structure of MOF-74, the in situ formed MOF arrays and the synergistic effect of Ni and Fe, outstanding water oxidation activity is obtained in alkaline electrolytes with an overpotential of 223 mV at 10 mA cm⁻².
