The invention discloses carbon-coated TiO 2 A preparation method of a nanotube material belongs to the technical field of nanocomposite materials. The invention uses potassium permanganate and ammonium fluoride as raw materials, adopts a hydrothermal method to prepare MnO firstly 2 Nanowire template material, then hydrolyzing in MnO by isopropyl titanate 2 Nano TiO coated on the surface of the nano wire 2 Further coating carbon by a dopamine polymerization carbonization method, and finally reacting with MnO by sodium thiosulfate in an acid environment 2 By chemical reaction of 2 Template to obtain carbon-coated TiO 2 A nanotube material. The invention provides carbon-coated TiO 2 The template preparation method of the nanotube material has the advantages of simple synthesis process, mild reaction conditions, low cost, stable and adjustable nanotube structure and suitability for large-scale synthesis. |
