Abstract Proton exchange membrane water electrolyser (PEMWE) possesses great significance for the production of high purity hydrogen. To expedite anodic oxygen evolution reaction (OER) that involved multiple electron–proton‐coupled process, efficient and stable electrocatalysts are highly desired. Currently, noble‐metal Ir‐based materials benchmark anode due to its corrosion‐resistant property favourable combination activity/stability. However, large‐scale deployment PEMWE is usually...
Zn metal with high specific capacity and low redox potential is deemed to be an ideal anode material for aqueous zinc-ion batteries (ZIBs).
