“…Two-dimensional (2D) nanostructured transition-metal dichalcogenides (TMDs) have shown numerous promising applications in energy storage and conversion field. , As a typical member, molybdenum disulfide (MoS 2 ) has aroused widespread research effort in the exploration of its application in electrochemical energy storage and conversion systems, because of its fascinating catalytic properties. , Among various MoS 2 -based nanostructures, such as nanosheets, nanospheres, nanotubes, and mesoporous/microporous structures, 2D layered nanosheets stand out, because of their highly exposed active edge sites and fast ion diffusion paths. − However, the inherently low electrical conductivity and easy aggregation of MoS 2 nanosheets severely hamper their further development . Various approaches have been reported in recent years to solve the above issues, in which the composite strategies between the layered MoS 2 nanosheet and conductive carbonaceous materials are considered to be a promising approach …”
