摘要： A molybdenum disulfide/graphene/carbon composite material having a hierarchical pore structure includes a composite nanofiber having a diameter of 60 to 500 nm. The composite nanofiber 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 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 accounts for 25% to 60%, and a mesoporous structure accounts for 40% to 75%. The microporous structure is distributed on the surface of the nanofiber and the pore wall of the mesoporous structure.

摘要： The method of synthesizing carbon nanorods (CNRs) and carbon nanowires (CNWs) involves carbonization of a resorcinol-formaldehyde cross-linked precursor gel. The first stage is the synthesis of resorcinol-formaldehyde cross-linked precursor gel. The second stage is carbonization of the gel by heating the gel in a furnace under the flow of nitrogen gas at 500° C. for three hours. The third stage involves activating the carbon by heating the carbon gel in a furnace under the flow of carbon dioxide gas for one hour at 700° C. to form the CNRs and CNWs.
