Elucidating the Role of Alkali‐Metal Cations in Nickel Oxide OER Catalysts Under Mild pH Conditions by Operando X‐Ray Absorption Spectroscopy
ions not only lower the Ni oxidation onset potential but also facilitate ion transport during water oxidation. This work provides valuable mechanistic insight into cation-dependent OER enhancement and offers guidelines for the design of next-generation electrocatalysts tailored for near-neutral environments.
