Sulfur‐Vacancy Anchoring Suppresses Dynamic Surface Reconstruction in Ni‐Doped ZnS Nanospheres to Trigger the Lattice Oxygen Mechanism (Small 20/2026)

Oxygen Evolution Reaction Although dynamic structural reconstruction of sulfides under oxygen evolution reaction (OER) conditions is widely considered the origin of high activity, it obscures the precise role of sulfur vacancies in catalytic enhancement. Sulfur vacancies acting as anchoring centers enable controlled reconstruction, offering critical insights into the intrinsic OER mechanism of transition-metal sulfide catalysts.
