Zusammenfassung:	The invention discloses a preparation method and application of iron-cobalt-doped porous carbon nanofibers, FeCo-MOFs and ZIF-8 MOFs are assembled into electrospun nanofibers, then the electrospun nanofibers are calcined to obtain the iron-cobalt-doped porous carbon nanofibers, FeCo-MOFs serve as a main supply source of bi-components, ZIF-8 is evaporated after pyrolysis, a large number of pore structures are left, and the iron-cobalt-doped porous carbon nanofibers are obtained. The synergistic effect between the two components can effectively improve the catalytic effect of the catalyst, and a large number of pore structures can provide a larger specific surface area for the material, so that more active sites are formed. Therefore, the iron-cobalt-doped porous carbon nanofiber material disclosed by the invention has more excellent electro-catalytic performance, and the preparation method disclosed by the invention has the advantages of low raw material price and simplicity in operation, and can be used for l
