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.
