Large electronegativity differences between adjacent atomic sites activate and stabilize ZnIn₂S₄ for efficient photocatalytic overall water splitting.

ABSTRACT: Photocatalytic overall water splitting into hydrogen and oxygen is desirable for long-term renewable, sustainable and clean fuel production on earth. Metal sulfides are considered as ideal hydrogen-evolved photocatalysts, but their component homogeneity and typical sulfur instability cause an inert oxygen production, which remains a huge obstacle to overall water-splitting. Here, a distortion-evoked cation-site oxygen doping of ZnIn₂S₄ (D-O-ZIS) creates significant electronegativity differences between adjacent atomic sites, with S₁ sites being electron-rich and S₂ sites being electron-deficient in the local structure of S₁-S₂-O sites. The strong charge redistribution character activates stable oxygen reactions at S₂
