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 Cu2+-doped ZnIn2S4 nanorings show highly preserved morphology, and demonstrate high visible-light-driven photocatalytic activity for H2 evolution in water splitting.
