Abstract

Besides thermodynamic limitations, kinetic energy barriers hindered further exploration of synthesis mechanisms and functional nanomaterials. The breakthrough of kinetic energy barriers in cation exchange from CuInX₂ (X = S, Se) to Cu/In dual-doped CdX and ZnX SNCs was achieved unprecedentedly by an effective surface-vacancy-engineering-initialized cation exchange (SVEICE) strategy. The key of this strategy was sequentially creating Cu and In vacancies on multi-component SNC surfaces. In addition, this strategy possessed outstanding versatility in other multi-component SNC cation exchange processes.
