The invention belongs to the field of nano material preparation, and discloses a modified titanium nitride nanotube with Ni-MOF as a precursor as well as a preparation method and the application of the modified titanium nitride nanotube. The method comprises the following steps: dissolving a nickel source and an organic ligand in an organic solvent, filtering and then drying, mixing the obtained Ni-MOF precursor with a titanium source dissolved in the solvent, reacting at 100-200 DEG C, cooling, filtering, washing and drying after the reaction is finished, carrying out air burning at 250-550 DEG C, mixing the obtained intermediate product with a carbon source to obtain a precursor, and nitriding the precursor at 600-900 DEG C to obtain the nickel-doped titanium nitride nanotube, namely the modified titanium nitride nanotube. The nickel-doped titanium nitride nanotube disclosed by the invention has a coral-like tubular structure and a relatively large specific surface region, and is good in conductivity, stabi
