在Fe~(2+)的诱导下，在泡沫镍上原位生长了有序的NiFe-MOF-74，并直接用作OER电催化剂。在碱性电解液中，由于MOF-74固有的开孔结构、原位形成的MOF阵列以及Ni和Fe的协同作用，在10 mA cm−2时具有良好的水氧化活性，其过电位为223 mV。
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.
