Abstract

The performance of ZnO/Pt/Cd_1−yZn_yS (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.
