Abstract：

Hydrogen energy has become one of the recognized clean energy sources worldwide due to its advantages such as low cost, renewable energy, and green environmental protection. Electrolytic water is currently one of the most promising solutions for providing hydrogen fuel. Nickel iron bimetallic electrocatalysts have abundant sources, low cost, clean and pollution-free properties, and strong catalytic performance, This article mainly reviews the development and research of bimetallic nickel iron oxides and nickel iron alloys in recent years, and explores their synthesis methods, properties, and stability in depth.

Key Words：

electrochemistry; bimetallic nickel ferroelectric catalyst; hydrogen evolution reaction; oxygen evolution reaction
