Highlights A bimetallic lanthanum-nickel oxysulfide based on a La2O2S prototype was developed as a precatalyst for the electrochemical alkaline oxygen evolution reaction (OER). The in situ, ex situ, and theoretical investigations demonstrated that the precatalyst underwent a deep OER-driven reconstruction into a porous heterostructure where NiOOH nanodomains were uniformly separated and confined by La(OH)3 barrier. Oxyanion (SO4 2−) was steadily adsorbed on the surface of this in situ reconstructed NiOOH/La(OH)3 heterostructure, enabling it for enhanced OER activity and durability.
