Abstract

The solar-to-hydrogen generation from the TiO₂-CdS-ZnS-MoS₂ (TCZM) heterointerface was demonstrated. We found that a Pt-free CdS quantum dot-sensitized TiO₂ mesoporous electrode with a metallic-type 1T MoS₂ co-catalyst resulted in 0.11 ml cm^-2 h^-1 H₂ fuel generation in unassisted potential mode, which was strikingly improved to 1.47 ml cm^-2 h^-1 under 1 V applied potential.
