A bimetallic NiFe MOF directly grown on NiFe foam as an oxygen evolution reaction catalyst

A NiFe-MOF in situ grown on an NFF substrate was successfully prepared. The prepared NiFe-MOF/NFF catalyst has an overpotential of 233.0 mV at 10 mA cm −2 , which is superior to those of the corresponding Ni-MOF/NFF and Fe-MOF/NFF.
