Synthesis and Application in Photocatalytic Hydrogen Production of Layered MoS2

Abstract

With the consumption of energy and the destruction of the environment by mankind, mankind is now facing a serious energy and environmental crisis. In order to solve this situation, photocatalytic hydrogen production from water will become an effective way. MoS2 shows a good potential for photocatalytic hydrogen production, and the research in this paper will help to develop efficient photovoltaic hydrogen production materials. Two-dimensional MoS2 is a layered transition metal compound similar to graphene. For its advantages, such as large specific surface area, suitable band gap, high catalytic activity of hydrogen evolution by edge suspension bond and strong photocorrosion resistance, it shows good application potential in photocatalytic hydrogen production. This paper summarizes the research progress of layered MoS2 in photocatalytic hydrogen production in recent years. The preparation method of two-dimensional layered MoS2, the structure and properties of MoS2, and the application of the composite system formed by MoS2 and other semiconductor materials in photocatalytic hydrogen production are introduced. Besides, the author discussed the development prospects of MoS2.
