Chloride‐Mediated Electron Buffering on Ni‐Fe Anodes for Ampere‐Level Alkaline Seawater Electrolysis
Advanced Functional Materials, EarlyView.Utilizing abundant chloride ion (Cl−) of seawater, the small organic molecule (SOM) layer on the electrocatalyst surface is converted to SOM‐Cl layer. Meanwhile, the conjugated structure of SOM is modified. SOM‐Cl layer can effectively mitigate the damage caused by the highly oxidative environment.
