According to the experts, the metal titanium is cleaned and etched, and then the metal titanium is immersed in an oxidation solution of peroxotungstic acid sol and hydrogen peroxide solution and maintained at a certain temperature for a period of time to obtain nano-thin films of titanic acid and peroxytungstic acid formed by in-situ growth and deposition of crystals. The nano-film is finally calcined to obtain a titanium oxide - tungsten oxide nanocomposite film on the surface of metal titanium. The nano-ribbon width of the obtained composite film is between 10-150 nm, and the length is between 0.5-20 μm. Compared with the prior technique, the preparation method is simple and feasible, and is suitable for large-scale industrial production.
