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

Hierarchical MoS/graphene (MoS/G) has been widely researched in energy storage supercapacitors. The combination of MoS 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 MoS/G nanostructures in supercapacitor applications is summarized by classifying the materials into MoS/G nanospheres, MoS/G nanosheets, and MoS/G-based ternary composite. The description of the structural characteristics and electrochemical performance gives a clear and profound understanding of hierarchical MoS/G nanostructures as a supercapacitor material. In addition, further research prospects of hierarchical MoS/G are suggested.
