How to extend ultraviolet photocatalysts to the visible-light region is a key challenge for solar-driven photocatalysis. Herein, we show that ultraviolet ZnO photocatalysts can present high visible-light photocatalytic activity when combined with CuO quantum dots (QDs; <3 nm). Theoretical analysis demonstrates
