| description | The embodiment of the invention discloses a preparation method and application of a nitrogen-phosphorus-sulfur doped material. The preparation method comprises the following steps: dissolving 0.3-0.9 part by mass of PAN, 0.3-0.9 part by mass of ZIF-8 and 0.3-0.9 part by mass of triphenylphosphine sulfur in 5-11 parts by mass of DMF, and fully stirring to prepare a shell spinning solution; dissolving 0.8-2.3 parts by weight of PMMA (polymethyl methacrylate) in 3-10 parts by weight of DMF (dimethyl formamide), and stirring to prepare core layer liquid; stirring the shell layer spinning solution and the core layer solution for 12-15 hours, then carrying out coaxial spinning, then pre-oxidizing spun fibers at the temperature of 100-200 DEG C for at least 1 hour, carrying out carbonization pyrolysis at the temperature of 800-1000 DEG C, carrying out heat preservation for at least 1 hour, and then naturally cooling to obtain the nitrogen, phosphorus and sulfur doped hierarchical pore carbon nanofiber material.
