Abstract

An Ag₂ZnGeO₄ photocatalyst was fabricated by ion-exchange reaction between amorphous Zn₂GeO₄ suspension and Ag⁺ solutions. The Ostwald ripening effect induced the formation of hierarchical hollow spheres. Compared with the reference bulk Ag₂ZnGeO₄, the hierarchical Ag₂ZnGeO₄ hollow spheres showed enhanced photocatalytic activity.
