Herein, a NiFe (hydr)oxide-based electrode that undergoes operation at 50 V is introduced as an effective and durable electrocatalyst under neutral conditions. The electrocatalyst produced on the surface of the foam is examined through several methods. All of the mentioned methods indicate the presence of various NiFe (hydr)oxides with different phases on the NiFe foam surface. For the anodized NiFe foam at pH 7, the overpotential for the onset of OER and the activity at 1 mA/cm(2) are recorded at 440 and 580 mV, respectively. In addition, the effects of anodization potentials and electrochemically active surface areas are discussed.
