Title:
MOLYBDENUM DISULFIDE/GRAPHENE/CARBON COMPOSITE MATERIAL AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/036219
Kind Code:
A1
Abstract:
A molybdenum disulfide/graphene/carbon composite material having a hierarchical pore structure, consisting of a composite nanofiber (1) having a diameter of 60 to 500nm. The composite nanofiber (1) comprises, in mass percentage, 3% to 35% of molybdenum disulfide, 0.2% to 10% of graphene, and 60% to 95% of carbon. The composite nanofiber (1) has a hierarchical pore structure distributed along the axial direction, and has a pore diameter continuously distributed between 0.1 nm and 5 μm and an average pore diameter between 1.5 nm and 25 nm. On the basis of the pore volume, in the hierarchical pore structure, a micropore structure (3) accounts for 25% to 60%, and a mesoporous structure (2) accounts for 40% to 75%. The microporous structure (3) is distributed on the surface of the nanofiber and the pore wall of the mesoporous structure (2). The composite material has advantages such as high specific surface area, well developed pore structure, controllable pore size and structure, and wide range of application.
