Abstract:Graphene-like molybdenum disulfide (MoS2), which is composed of a monolayer or few layers of MoS2, is a new two-dimensional layered material which has attracted considerable attention in the fields of field effect transistors, sensors, photoelectric devices, lithium batteries, and supercapacitors because of its ultra-thin thickness and specific physical and chemical properties, including electronic structure, chemical activity and optical properties. In addition, because of its effective activity for hydrogen evolution features, huge surface area and excellent chemical stability, two dimensional MoS2 becomes a good catalyst for hydrogen evolution, especially monolayers MoS2 having a band gap of 1.9eV and direct band gap structure, becoming photocatalytic materials research focuses. The review briefly describes the basic structure and physical and chemical properties of two-dimensional MoS2, then details the catalyst used in hydrogen production aspects. Its potential advantages and challenges of the prospects as single photocatalyst are discussed. Finally, the outlook for the research of two-dimensional molybdenum disulfide nanomaterial is proposed.
