Abstract: Highly efficient, stable, and low cost electrocatalysts for the oxygen evolution reaction (OER) to evolve oxygen gas are key to water-splitting in alkaline media. Recently, researchers have designed advanced Ni-Fe-based OER electrocatalysts with higher catalytic activity for efficient and durable water electrolysis. In this review, we present the latest progress in advanced Ni-Fe-based materials with excellent activity and stability, including Ni-Fe-based alloy, oxide and layered double hydroxide and their composites. Furthermore, detailed OER electrocatalysis mechanisms for Ni-Fe based materials are discussed to provide insight into the nature of active catalytic sites as well as the effect of Fe incorporated in Ni-based electrocatalsyts. Finally, it is also pointed out that the future studies should focus on the development of novel Ni-Fe-based materials with superior catalytic activity and the detailed mechanisms responsible for improved OER activity.

Key words: Ni-Fe based materials, catalyst, electrolysis, oxygen evolution reaction, reaction kinetics
