Zusammenfassung:The invention discloses a cobalt-based ferrite and carbon nanotube composite material and a preparation method and application thereof, and relates to the technical field of composites.The preparation method comprises the steps that carbon nanotubes and a dispersing agent are added into a first organic solvent, and a first solution is obtained; adding cobalt nitrate hexahydrate and ferrous sulfate heptahydrate into a second organic solvent to obtain a second solution; adding the second solution into the first solution, and adding an organic ligand to obtain a reaction solution; transferring the reaction solution into a hydrothermal reaction kettle, and carrying out hydrothermal reaction at a first preset temperature for a first preset time to obtain a precursor; and putting the precursor into a tubular furnace, carrying out heat preservation at a second preset temperature for a second preset time in the atmosphere of argon, and naturally cooling to obtain the cobalt-based ferrite and carbon nanotube composite
