specific Embodiment approach 1
[0009] Specific embodiment one: the preparation method of the titanium dioxide film electrode of the present embodiment is carried out as follows: one, the pretreatment of titanium plate: be that the concentrated nitric acid of 65% and mass concentration are 40% hydrogen fluoride solution by volume ratio to be 1 : 1 ratio, put the titanium sheet into the mixed solution and soak for 2 to 5 seconds, take it out and rinse it with distilled water; 2. Put the treated titanium sheet into the electrolyte, the titanium sheet is used as the anode, and the copper is used as the cathode. The input current intensity is 1~20A / dm 2 1. Direct current with a voltage of 100-280V for 5-50 minutes; 3. Wash the electrolyte covering the titanium dioxide film with distilled water, and after drying, put the dried titanium dioxide film into a concentration of 0.1-1mmol / L Soak and sensitize in the ethanol solution of the sensitizer for 12 hours under the condition of 25-45° C., then take out the film,...
specific Embodiment approach 2
[0011] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in Step 1, the titanium sheet is put into the mixed liquid and soaked for 3 seconds. Other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0012] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 is that the current in step 2 is 2-19A / dm 2 , The voltage is 120-240V DC for 10-45 minutes. Other steps and parameters are the same as those in Embodiment 1.
