Research progress on non-precious metal catalysts for hydrogen production by anion exchange membrane electrolysis
As an important green energy,hydrogen energy is an important guarantee to achieve carbon neutrality and carbon peak.Anion exchange membrane electrolytic cell combines the advantages of alkaline electrolytic cell and proton exchange membrane electrolytic cell,and can use non-precious metal catalyst combined with renewable energy,which is expected to break the bottleneck of high cost of green hydrogen preparation.In this paper,the recent research progress on the stability of non-noble metal catalysts for water electrolysis by AEM is reviewed.The dissolution and degradation behavior of catalyst metals are discussed,and the mechanism of oxygen evolution reaction on catalysts is emphasized.
