Novel Method of MoS2 Decorated CdS Core‐shell Nano‐Heterojunctions for Highly Efficient and Stable Hydrogen Generation.

Exploitation of efficient and stable photocatalyst for water splitting is pressing to solve the energy crisis. Four CdS@MoS2 nano‐heterojunctions were prepared by a single precursor thermal decomposition combined with one‐step hydrothermal method. The morphology of the prepared samples is spherical and has obvious core‐shell structure interface. The photocurrent of CdS@MoS2‐2 wt% is the largest, which is more over 40 times that of the pure CdS. In addition, CdS@MoS2‐2 wt% had superior photocatalytic H2 generation activity (20.23 mmol g−1 h−1) without any noble metal as a cocatalyst under visible light and show marked photocatalytic durability after a continuous test for 16 hours. This work provides a new insight for the design of core‐shell nano‐heterojunctions for other metal sulfide composites. [ABSTRACT FROM AUTHOR]
