Abstract

The invention discloses a hollow carbon nanosphere material and a preparation method thereof, and belongs to the field of an inorganic material. According to the method, a controllable polystyrene nanoparticle is taken as a template, an organic polymer coating is coated on the surface of the polystyrene nanoparticle, and then the hollow carbon nanosphere material of which the carbon layer thickness is adjustable is obtained by adopting a high-temperature template removing method. The method is simple and feasible, economical and reasonable, and applicable to industrial production, and the sizes of carbon spheres and the thickness of the shell can be regulated and controlled.

Description

technical field [0001] The invention relates to a hollow carbon sphere nano material and a preparation method thereof, belonging to the field of inorganic materials. Background technique [0002] In recent years, the microscopic morphology modification of carbon materials has become a research boom. Among them, hollow carbon nanospheres (HCSs) have attracted much attention due to their unique properties, such as high specific surface area, excellent electrical conductivity, and thermal stability. HCSs have promising applications in various fields, such as adsorption, lithium-ion batteries, fuel cells, and catalysis, and can also be used as units of complex structures, such as carbon material parts used as pyrotechnic agents. In recent years, scientists have devoted great efforts to the synthesis of HCSs. However, the preparation methods of most HCSs are relatively complicated, thus, it is very unfavorable for industrial large-scale continuous production. [0003] In the d...
