Abstract

The invention discloses a method for rapid solvent-free preparation of heteroatom-doped graphitized carbon with high specific surface area. The method comprises the following steps: carrying out grinding and mixing on organic sulfonate and / or organic phosphonate and oxygen-containing organic polymer; then putting a mixture in protective atmosphere, and carbonizing at high temperature; washing and drying a carbonized product to obtain the heteroatom-doped graphitized carbon with the high specific surface area and mesopore and micropore structures. The method has the advantages of simple operation, no need of solvent, high yield and controllable heteroatom content; in addition, the production cost is greatly reduced, and industrial production is facilitated.
