In situ construction of a heterojunction over the surface of a sandwich structure semiconductor for highly efficient photocatalytic H evolution under visible light irradiation.

Developing a heterostructure on the surface of a "sandwich" structure semiconductor is essential for full utilization of its heterojunction function and hence for designing efficient solar energy conversion systems. Here, we show that 2D-2D MoS/MnSbS heterostructure composites are designed for the first time and successfully synthesized by a simple in situ calcination pathway. Under visible light irradiation, the ca.

Large-scale preparation of heterometallic chalcogenide MnSbS monolayer nanosheets with a high visible-light photocatalytic activity for H evolution.

Free standing MnSbS 2D monolayer nanosheets were developed by a simple calcination of the neutral hydrazine molecule bridged chalcogenide, and were found to display a highly efficient and stable activity for photocatalytic hydrogen evolution from water under visible light irradiation (420-730 nm).
