Visible light-driven photocatalytic activity of wide band gap ATiO3 (A = Sr, Zn and Cd) perovskites by lanthanide doping and the formation of a mesoporous heterostructure with ZnS QDs

A mesoporous type-II heterostructure, Dy-doped CdTiO 3 /ZnS QDs, was prepared. Taking advantage of the large surface area and considerable suppressing of the charge carrier recombination, this photocatalyst exhibits excellent performance for the degradation of MB and BPA.
