The invention discloses a heat-conducting and wave-absorbing composite material as well as a preparation method and application thereof, the heat-conducting and wave-absorbing composite material Fe3N/Fe4N (at) C is a composite material formed by simultaneously wrapping Fe3N and Fe4N with honeycomb carbon, the composite material is granular, the particle size of the composite material is 40-80nm, and the specific surface area of the composite material is 45-80m < 2 >/g. An MOF metal organic framework material is used as a precursor, the high-dispersion and high-stability honeycomb carbon coated Fe3N and Fe4N heat-conducting and wave-absorbing composite material is prepared by regulating and controlling the temperature and nitrogen potential, the synthesized heat-conducting and wave-absorbing composite material has a rough surface and a fine structure, electromagnetic waves can be scattered and dispersed through the structure, and the heat-conducting and wave-absorbing composite material has a good heat-conduct
