Suppressing Cathode Corrosion Induced by Impurity Cations in Alkaline Water Electrolyzers

Angewandte Chemie, EarlyView.
Impurity Fe species in electrolyte accelerate cathodic corrosion in alkaline electrolyzers by promoting peroxide formation. A strongly Lewis acidic CeOx protection layer stabilizes interfacial electronic structure via Fe−CeOx interactions, scavenges reactive oxygen species, and suppresses Fe accumulation, enabling stable Ni cathodes under universal ...
