Advances and Enhancement Strategies in Nickel-Based Electrocatalysts for Oxygen Evolution Reaction

Nickel-based materials have garnered significant attention as one of the most promising oxygen evolution reaction (OER) electrocatalysts in the field of alkaline water electrolysis for hydrogen production. This review systematically organizes the application examples and research trends of nickel-based OER electrocatalysts in alkaline water electrolyzers. We analyze the key factors affecting the performance of the electrocatalysts, including the intrinsic mechanisms of their catalytic activity and stability, and propose a series of innovative strategies for performance optimization. It is hoped that this will facilitate their large-scale commercial application in alkaline water electrolysis.
