Uniform single‐crystalline quaternary sulphide nanoring photocatalysts are synthesized via the copper‐ion‐induced Kirkendall effect and is followed by a cation exchange reaction. The obtained Cu 2+ ‐doped ZnIn 2 S 4 nanorings show highly preserved morphology, and demonstrate high visible‐light‐driven photocatalytic activity for H 2 evolution in water splitting.
