HOLLOW CARBON SPHERE WITH MULTI-STAGE PORE STRUCTURE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/150855
Kind Code:
A1
Abstract:
The present invention relates to a hollow carbon sphere with a multi-stage pore structure. The hollow carbon sphere is of a multi-stage pore structure, and has micropores, mesopores and macropores, wherein the pore diameter of the micropores is not greater than 2 nm, the pore diameter of the mesopores is distributed between 2-50 nm, and the pore diameter of the macropores is greater than 50 nm; the pore volume contributed by the micropores is 0.047-0.30 3/g; the pore volume contributed by the mesoporous is 0.15-0.49 cm3/g; the pore volume contributed by the macropores is 0.07-0.80 cm3/g; and the grain size of the hollow carbon sphere is 2.5-6.5 μm, the wall thickness thereof is 5-8 nm, and the specific surface area thereof is 443.23 m2/g. Further provided is a method for preparing the material. The carbon sphere provided by the invention has the characteristics of thin walls, a high porousness, a high specific surface area, etc., and these can enhance the application performance thereof.
Moreover, the present invention has simple steps, is controllable, has low costs, is suitable for industrial production and can be applied across a wide range of fields.
