Abstract

The invention relates to a bio-ene charcoal material and a preparation method thereof. According to the invention, a powdery biomass raw material is impregnated with a mixed water solution of phosphoric acid and sulfate; filtering is carried out, and the obtained material is dried by dipping; the material is activated for 60-150min under a temperature of 200-500 DEG C in a protective atmosphere; the activated biomass raw material is heated to a temperature of 1000 DEG C in a protective atmosphere, and the temperature is maintained for 10-40min; the material is heated to a temperature of 1200-1400 DEG C, and the temperature is maintained for 10-30min, such that the biomass raw material is catalytically charred, and an intermediate product is obtained; the obtained intermediate product is cooled, and is washed with ultrapure water; filtering is carried out, and the obtained product is dried; a mixed water solution of hydrochloric acid and / or hydrofluoric acid and ethylenediaminetetraacetic acid is used for dusting and for carrying out an activation treatment for 60-120min; filtering is carried out; and the obtained material is heated and dried, and is crushed, such that the bio-ene charcoal material is obtained. The XRD diagram of the material shows diffraction peak at 26 DEG, such that the material is a charcoal material with a graphitized structure. The material has the characteristics of high specific surface area, developed cavities, good conductivity, high electrochemical activity, and good charge and discharge stability.

Description

technical field [0001] The invention relates to the technical field of carbon materials, in particular to a bio-ene carbon material and a preparation method thereof. Background technique [0002] Due to the advantages of light weight, excellent physical and chemical stability, conductive heat transfer, heat resistance, heat resistance, and corrosion resistance, carbon materials have become indispensable materials in the development of the national economy.
