Remarkable improvement in visible-light induced hydrogen generation by ZnO/Pt/Cd1−yZnyS heterostructures through substitution of N and F in ZnO†
Abstract
The performance of ZnO/Pt/Cd1−yZnyS (y = 0.0, 0.2) heterostructures in generating hydrogen on visible light irradiation is substantially improved if ZnO is co-substituted with N and F, since such anion substitution results in intense visible light absorption and a decrease in the band gap.
