Biomass carbon microsphere, preparation method, supercapacitor and application

Abstract

The invention belongs to the technical field of carbon materials, and discloses a biomass carbon microsphere, a preparation method, a supercapacitor and application. The preparation method of the biomass carbon microsphere comprises the following steps: fermenting in afruit wine saccharomycetes sulfur-containing sucrose solution; adding a certain amount of glutaraldehyde and sulfur into the system, and carrying out ultrasonic treatment; transferring the solution into a hydrothermal kettle, reacting to obtain a brown product, and performing suction filtration, washing and drying; and putting the product into a tubular furnace, cooling, washing and drying in a nitrogen atmosphere to obtain the final carbon microsphere with an internal fine structure. The method has the advantages of simplicity, convenience, easiness in operation, environmental friendliness, wide applicability and the like. The method is suitable for biomass carbon microspheres, has more excellent application performance,and is simple, convenient and easy to operate and easy for mass production. The carbon microspheres prepared by the method show ultrahigh capacitance performance; the method is simple and convenientto operate, environment-friendly and easy for batch preparation; and the method is suitable for different types of saccharomycetes.

Description

technical field [0001] The invention belongs to the technical field of carbon materials, and in particular relates to a biomass carbon microsphere, a preparation method, a supercapacitor and an application. Background technique [0002] At present: Carbon materials have been widely used in many fields due to their excellent mechanical strength, chemical inertness, and excellent electrical and thermal conductivity. Porous carbon microspheres have unique characteristics such as regular geometry, controllable size, fine structure, and significant high packing density and high specific surface area, endowing carbon materials with new structural properties and expanding their application fields. With the continuous improvement of the demand for high-end products, the construction and regulation of the fine structure inside the microsphere is the top priority. Although researchers have made a lot of efforts, the preparation of carbon microspheres with fine internal structure is s...
