Method for preparing heteroatom-doped carbon material at room temperature

Abstract

The invention relates to a method for preparing a heteroatom-doped carbon material at a room temperature. The method comprises the following steps: mixing a halogenated macromolecule and strong base with a strong polar solvent so as to obtain a mixture, grinding the mixture at the room temperature, and directly cleaning and drying after completion of grinding, so as to obtain the heteroatom-doped carbon material, wherein the halogenated macromolecule is polyvinylidene difluoride, polyvinylidene chloride or polyvinyl chloride, the strong base is alkali (earth) metal hydroxide, alkali (earth) metal alkoxide, alkali (earth) metal sulfide, alkali (earth) metal amides or alkali (earth) metal nitride, the strong polar solvent is N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide or nitrogen methyl pyrrolidone and the room temperature refers to 10-40 DEG C. According to the method, the raw materials are cheap and easy to obtain, the operation is simple, safety is high and the method is very suitable for industrial expanded production.

Description

technical field [0001] The invention belongs to the field of preparation methods of doped graphitized carbon materials. Background technique [0002] Carbon is one of the elements most closely related to human production and living activities. Its diverse electronic orbital characteristics make it rich in bonding hybridization forms, making it the only one that can complete the construction from zero-dimensional fullerene to One-dimensional carbon nanotubes to two-dimensional graphene to three-dimensional diamond and elements of various porous carbon materials. At present, two simple carbon forms, fullerene and graphene, have won the Nobel Prize in 1996 and 2010 respectively, which is enough to prove the importance of carbon material research. In recent years, the research on carbon materials and the corresponding production are in full swing, and carbon materials can be found in many fields, which also makes the preparation of carbon materials very important.

Problems solved by technology

The carbon material prepared by this method has a high structure and atomic regularity, which can be applied in electrical aspects, but its scale is limited.

(2) Pyrolysis method, that is, directly heating the reaction raw materials to cause polymerization, reformation, and defunctionalization under the condition of high-temperature energy input, and finally obtain a carbon material with high carbon content in the region of graphitization. This strategy Most of the prepared carbon materials are amorphous carbon materials, but they have rich pore structure and high plasticity, but the disadvantages of this method are also obvious, such as poor controllability compared with chemical vapor deposition method, in order to protect the environment , strict exhaust gas treatment is required in the process of defunctionalization
