Abstract
Band gap engineering of ZnO nanorods was achieved by introducing a core/shell geometry with the environmentally benign Ag2S sensitizer as the shell. Sensitizing ZnO with Ag2S resulted in substantially enhanced light absorption and photodegradation of MB under illumination of visible light, in comparison to Cd sensitizers, owing to the narrow band gap of Ag2S, thus unraveling the superiority of Ag2S as an efficient sensitizer to sensitize wide band gap semiconductors and the potential to supersede Cd-based sensitizers for eco-friendly applications.
