Abstract

The invention belongs to the field of preparation of inorganic semiconductor nanomaterials and discloses a preparation method of iron-doped titanium nitride nanotubes. The method comprises the following steps: adding ferric chloride and titanium oxysulfate at the ratio of amount of substance of (0.01 to 0.1) to 1, and a certain volume of absolute ethyl alcohol, butanediol and butyl ether into a high-pressure kettle with a polytetrafluoroethylene liner; reacting at temperature of 120 DEG C to 200 DEG C for 8h to 16h; after cooling, filtering, washing and drying; calcining at 300 DEG C to 500 DEG C to obtain iron-doped titanium dioxide; carrying out nitriding and calcining treatment to obtain the iron-doped titanium nitride nanotubes. The method is simple and easy to operate and raw materials are cheap, so that the iron-doped titanium nitride nanotubes can be produced in large scale; the obtained iron-doped titanium nitride nanotubes have relatively large specific surface area and good conductivity and stability. The iron-doped titanium nitride nanotubes can be applied to the fields of diluted magnetic materials, dielectric and microwave absorption materials, electrode catalyst carriers and heat-conducting materials and the like.
