Abstract
The invention discloses a method for preparing tungsten-trioxide nanotubes. The method includes the following steps that ammonium tungstate is dissolved into distilled water according to the mass ratio of (1-2):100, and an ammonium tungstate water solution is prepared; an anodized aluminum template is soaked into the ammonium tungstate water solution for 15-20 days at the soaking temperature of 30-40 DEG C; the anodized aluminum template is taken out of the ammonium tungstate water solution, and put into a muffle furnace to be gradually heated to 500-540 DEG C, the heating rate of the muffle furnace is 40 DEG C/min, and the temperature is kept for 4-5 h; the treated anodized aluminum template is gradually cooled to be at the room temperature in the muffle furnace, oxide on the surface of the anodized aluminum template is collected through a scraper, and the tungsten-trioxide nanotubes are obtained. By means of the method, the adhesiveness of the ammonium tungstate on the anodized aluminum template is improved, the tungsten-trioxide nanotubes in the regular shapes are prepared accordingly, and the yield of the tungsten-trioxide nanotubes is increased.
