Abstract

The invention discloses a mesoporous nickel oxide and carbon composite nano-material and a preparation method thereof. The mesoporous nickel oxide and carbon composite nano-material is composed of 1% of oxygen atom, 2.72-3.75% of nickel atom and 96.28-95.25% of carbon atom; the specific surface area of the material is 435.5-800 m2 / g, the pore volume of the material is 1.08-1.5 cm3 / g, and the aperture of the material is 2.5-12.0nm. The mesoporous nickel oxide and carbon composite nano-material of large specific surface area, pore volume and aperture is prepared by a self-assembly method induced by evaporation by taking a nonionic surfactant as a template and an inorganic nickel salt as a nickel source. The mesoporous nickel oxide and carbon composite nano-material can be used as electrode material for preparing super capacitor. The preparation method is simple, raw materials are simple and easy to obtain, and the method is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of inorganic material synthesis and preparation of electrode materials, and in particular relates to a mesoporous nickel oxide / carbon composite nanometer material and a preparation method thereof. Background technique [0002] As a new type of energy storage system between traditional capacitors and lithium-ion batteries, supercapacitors have significantly higher power density than lithium-ion batteries, and energy density is 10 to 100 times that of traditional capacitors. Long, wide operating temperature range, economical, environmentally friendly and maintenance-free. As an emerging solid porous material, mesoporous materials not only have important characteristics such as uniform pore size, orderly arrangement, and continuous adjustment of pore diameter within 2-50nm, but also have large pore volume, high specific surface area, and pore size. The surface can be physically adsorbed or chemically modified and has go...
