Exploring the Potential of Ni‐Based Hydrogen Evolution Catalysts in Anion Exchange Membrane Water Electrolyzer

The pressing need for sustainable hydrogen production has spotlighted anion exchange membrane water electrolyzer (AEMWE) as a promising technology, due to its potential for cost-effective and efficient hydrogen evolution. Nickel (Ni)-based catalysts have emerged as pivotal players in this domain, offering a compelling alternative to noble metal catalysts for the hydrogen evolution reaction (HER) in AEMWE. Despite their widespread use, challenges such as insufficient activity, conductivity, and long-term stability under alkaline conditions hinder their commercial scalability. This review provides a systematic exploration of Ni-based catalysts for HER in AEMWE, beginning with an in-depth analysis of design…
