Synthesis of MoS 2 -based nanostructures and their applications in rechargeable ion batteries, catalysts and gas sensors: a review.

Molybdenum disulfide (MoS 2 ) is a two-dimensional (2D) layered material with a graphene-like structure that has attracted attention because of its large specific surface area and abundant active sites. In addition, the compounding of MoS 2 with other materials can enhance the performance in applications such as batteries, catalysts, and optoelectronic devices, etc. MoS 2 is prepared by various methods, among which chemical deposition and hydrothermal methods are widely used. In this review, we focus on summarizing the applications of MoS 2 and MoS 2 composite nanomaterials in rechargeable ion batteries, catalysts for water splitting and gas sensors, and briefly outline the preparation methods.
