[0021] Example 1
[0022] The specific steps of preparation are:
[0023] Step 1. Put the metal titanium sheet as the anode and graphite sheet as the cathode in the electrolyte, and anodic oxidation for 2.5 hours at a DC voltage of 50V; wherein the purity of the metal titanium sheet is 99.9%, and the electrolyte is composed of 0.2wt% Ammonium fluoride, 1.6% by weight of water and the balance are mixed with ethylene glycol. Then place it in deionized water or distilled water for ultrasonic cleaning for 3 minutes and then dry. Then, the side that has been anodized is subjected to a second anodization under the same process conditions for 2.5 hours, and then it is washed and dried. Among them, the washing and drying treatments are cleaned with ethanol and then Drying at 50℃, the result is approximately figure 1 A shows an array of titanium dioxide nanotubes with a tube inner diameter of 90 nm and a tube length of 30 μm.

[0027] The specific steps of preparation are:
[0028] Step 1. Put the metal titanium sheet as the anode and the graphite sheet as the cathode in the electrolyte, and anodic oxidation for 2.3h at a DC voltage of 55V; wherein the purity of the metal titanium sheet is 99.99%, and the electrolyte is composed of 0.25wt% Ammonium fluoride, 1.7wt% of water and the balance are mixed with ethylene glycol. Then place it in deionized water or distilled water for ultrasonic cleaning for 3.5 minutes and then dry. Then, the side that has been anodized is subjected to a second anodization under the same process conditions for 2.3 hours, and then it is washed and dried. Among them, the washing and drying treatments are cleaned with ethanol. Drying at 50℃, the result is approximately figure 1 A shows an array of titanium dioxide nanotubes with a tube inner diameter of 95 nm and a tube length of 25 μm.

[0031] Example 3
[0032] The specific steps of preparation are:
[0033] Step 1. Put the metal titanium sheet as the anode and graphite sheet as the cathode in the electrolyte, and anodic oxidation for 2h at a DC voltage of 60V; wherein the purity of the metal titanium sheet is 99.9%, and the electrolyte is made of 0.3wt% fluorine. It is made by mixing ammonium hydroxide, 1.8wt% water and the balance of ethylene glycol. Then place it in deionized water or distilled water for ultrasonic cleaning for 4 minutes and then dry. Then, the side that has been anodized is subjected to a second anodization under the same process conditions for 2 hours, and then it is washed and dried. Among them, the washing and drying treatment is carried out after washing with ethanol for 50 Dry at ℃ to get figure 1 A shows an array of titanium dioxide nanotubes with a tube inner diameter of 100 nm and a tube length of 20 μm.
