Abstract

Anion Exchange Membrane Water Electrolysis In article number 2405468, EunAe Cho, Chanwon Jung, MinJoong Kim, and co-workers demonstrate that the ternary compositions of Fe-Co-Ni electrocatalysts correlate between the degree of crystallinity and oxygen evolution activity (OER). By analyzing 21 series of ternary compositions, the Fe-Co3-Ni electrocatalysts, which possess optimal composition and structural disorder, exhibit enhanced OER activity and stability, contributing to sustainable green hydrogen production.
