Recent advances in hierarchical MoS2/graphene-based materials for supercapacitor applications

Abstract

Hierarchical MoS₂/graphene (MoS₂/G) has been widely researched in energy storage via supercapacitors. The combination of MoS₂ with graphene not only provides high conductivity but also enhances the structural stability, which are critical factors determining the electrochemical performance for energy storage. In this review, the recent development of various hierarchical MoS₂/G nanostructures in supercapacitor applications is summarized by classifying the materials into MoS₂/G nanospheres, MoS₂/G nanosheets, and MoS₂/G-based ternary composite. The description of the structural characteristics and electrochemical performance gives a clear and profound understanding of hierarchical MoS₂/G nanostructures as a supercapacitor material. In addition, further research prospects of hierarchical MoS₂/G are suggested.
