Examples
Embodiment 1
[0020] Mix formamide and glycerin at a volume ratio of 1:1, use the mixed solvent to prepare a sodium fluoride solution with a concentration of 0.5% by weight, put the sodium fluoride solution into the reaction vessel, use the zirconium sheet as the anode, and the platinum sheet as the cathode , the distance between the anode and the cathode is 1.5cm, and the anodic oxidation reaction is carried out at room temperature with 90V direct current, and zirconia nanotubes are formed on the surface of the zirconium sheet. As the reaction progresses, the zirconia nanotubes formed on the surface of the zirconium sheet continue to fall off. After the reaction, the zirconium dioxide nanotubes sinking to the bottom of the reaction vessel were separated, washed with water, and dried at 105° C. to obtain the zirconium dioxide nanotube product.
Embodiment 2
[0022] Mix formamide and ethylene glycol at a volume ratio of 2:1, use the mixed solvent to prepare a solution of 0.5% potassium fluoride and 0.5% ammonium fluoride by weight, and add the fluoride solution to the reaction vessel. The platinum sheet was used as the anode, and the platinum sheet was used as the cathode, the distance between the anode and the cathode was 1.5 cm, and the anodic oxidation reaction was carried out at room temperature with 30V direct current. After the reaction, the zirconium dioxide nanotubes sinking to the bottom of the reaction vessel were separated, washed with water, and dried at 105° C. to obtain the zirconium dioxide nanotube product.
Embodiment 3
[0024] Mix formamide and ethanol at a volume ratio of 3:1, use the mixed solvent to prepare an ammonium fluoride solution with a concentration of 1.5% by weight, put the ammonium fluoride solution into the reaction vessel, use the zirconium sheet as the anode, and the graphite sheet as the cathode , the distance between the anode and the cathode is 1.5cm, and the anodic oxidation reaction is carried out at room temperature with 10V direct current. After the reaction, the zirconium dioxide nanotubes sinking to the bottom of the reaction vessel were separated, washed with water, and dried at 105° C. to obtain the zirconium dioxide nanotube product.
