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.
已证明从TiO2-CdS-ZnS-MoS2（TCZM）异质界面实现了太阳能到氢能的转化。我们发现，具有金属型1T MoS2助催化剂的无铂CdS量子点敏化TiO2介孔电极在无辅助电位模式下产生氢气燃料的速率为0.11 ml cm(-2) h(-1)，在1 V外加电位下显著提高到1.47 ml cm(-2) h(-1)。
