The oxygen evolution reaction (OER) is a rate determining step in water electrolysis, which requires higher overpotential to overcome kinetic barriers and electron transfer to complete the reaction. Therefore, the design of OER electrocatalysts with excellent activity and stability has significant economic and environmental significance. In this work, a series of nickel foam (M/NF) supported transition metal catalysts were prepared via a facile hydrothermal method. The structural, morphological and surface properties of as-prepared catalysts were investigated by XRD, SEM, TEM and XPS. Multiple characterization results reveal that the active components (Fe, Co, Ni, Cu, Zn) grown on the foam nickel substrate have diversity in crystal structures and morphologies, which may affect their electrocatalytic performance of oxygen evolution reaction. Among these catalysts, Fe/NF electrode exhibits superior electrochemical OER activity with a low overpotential (466 mV) at 10 mA cm−2 and a Tafel slope (95 mV dec−1) in 1 M PBS solution. Meanwhile, the above electrocatalyst shows excellent long-term stability for 50 h at a current density of 10 mA cm−2. Overall, the Fe/NF catalyst with low cost, high activity and stability show promise for application in oxygen evolution reaction.
