| titleOfInvention | Preparation method of high-sulfur-content nitrogen-sulfur co-doped asphalt-based carbon material |
| abstract | The invention relates to the technical field of carbon material preparation, and discloses a preparation method of a high-sulfur-content nitrogen-sulfur co-doped asphalt-based carbon material, which comprises the following steps: (1) placing absolute ethyl alcohol into a reaction kettle, dropwise adding a saturated sodium chloride aqueous solution into the absolute ethyl alcohol, heating and evaporating a solvent to prepare a sodium chloride template, (2) dissolving medium-temperature coal pitch into N-methyl pyrrolidone, placing the mixture into an oil bath, adding the sodium chloride template prepared in the step (1) and a nitrogen-containing compound into the mixture, uniformly stirring the mixture, heating and evaporating the N-methyl pyrrolidone, placing the mixture into a tubular furnace under the protection of hydrogen sulfide/argon mixed gas for heat treatment, and (3) cooling a sample subjected to the heat treatment in the step (2) to room temperature, taking out the sample, washing the sodium chloride template with deionized water, and drying the sodium chloride template to obtain the nitrogen-sulfur co-doped pitch-based carbon material. The high-sulfur-content nitrogen-sulfur co-doped asphalt-based carbon material prepared by the invention has the advantages of simple preparation process, rich raw material sources, high sulfur doping amount and easiness in large-scale preparation. |
