▎ 摘　　要

NOVELTY - Ternary composite material comprises hollow carbon nano-material, molybdenum disulfide nanosheet and graphene nanosheet. The hollow carbon nanomaterial is a concave bowl-shaped structure. The outer surface of the bowl wall of the bowl-shaped structure is loaded with the molybdenum sulfide nanosheet and forms a binary composite material. The graphene nano-sheets cover the binary composite materials to obtain the ternary composite material. The bowl wall is a hierarchical porous structure, which is provided with a large hole, micropores and mesopores. The hole diameter of the large hole is more than 50 nm, the aperture of the micropores is less than 2 nm, and the aperture of the mesopores is 2-50 nm. USE - The ternary composite material is useful in anode material of lithium ion secondary battery and electrode material of super capacitor, optical electronic device and solar battery. ADVANTAGE - The ternary composite material has high nitrogen loading and high oxygen loading. The method is simple, by simple hydrothermal method and heat treatment method, the graphene can be coated on the surface of CNB@MoS2 material, forming a 0D+ 2D + 2D " multi-dimensional system structure. It has high specific surface area, micropore, mesoporous and large hole of graded porosity. The raw material source of the composite material is simple and inexpensive. It is good for the transmission of electronic in the charging and discharging process. It provides a new method for potential electrochemical energy storage and conversion. The graphene nano-sheet not only can improve the conductivity of the material, but also can be used as a protective layer to improve the structure change in the long-term charging and DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation method of the ternary composite material comprising subjecting hollow carbon nano material and sulfur source to first hydrothermal reaction to obtain the binary composite material, subjecting the binary composite material, graphene and hydrazine hydrate to second hydrothermal reaction, and calcining to obtain the ternary composite material; (2) an electrode comprising current collector coated with the ternary composite material; and (3) a capacitor.
