Embodiment 1
[0013] (1) Cut the FTO glass into small pieces with a size of 10mm×25mm, and then immerse them in acetone, absolute ethanol, and deionized water in sequence, ultrasonically clean them for 2 minutes, and then dry them at 70°C for 2 hours.
[0014] (2) Dissolve 0.24 g of titanium sulfate in deionized water, and then add 5 ml of concentrated hydrochloric acid to prepare 20 ml of a uniform and transparent mixed solution. Transfer the mixed solution to an autoclave with a polytetrafluoroethylene liner, then place the two pieces of FTO glass pretreated in step (1) vertically in the solution, then seal the autoclave, Heat for 2h. After the reaction, the autoclave was naturally cooled to room temperature, the FTO glass was taken out, washed with deionized water and ethanol three times in sequence, and dried at 70°C for 2h. Finally, put the dried FTO glass into a tube furnace, raise the temperature to 500°C at a heating rate of 10°C / min, and keep it for 2h to obtain TiO 2 Nanorod and...

Embodiment 3
[0021] (1) Cut the FTO glass into small pieces with a size of 10mm×25mm, and then immerse them in acetone, absolute ethanol, and deionized water in sequence, ultrasonically clean them for 2 minutes, and then dry them at 70°C for 2 hours.
[0022] (2) Dissolve 0.24 g of titanium sulfate in deionized water, and then add 5 ml of concentrated hydrochloric acid to prepare 20 ml of a uniform and transparent mixed solution. Transfer the mixed solution to an autoclave with a polytetrafluoroethylene liner, then place the two pieces of FTO glass pretreated in step (1) vertically in the solution, then seal the autoclave, Heat for 1h. After the reaction, the autoclave was naturally cooled to room temperature, the FTO glass was taken out, washed with deionized water and ethanol three times in sequence, and dried at 70°C for 2h. Finally, put the dried FTO glass into a tube furnace, raise the temperature to 500°C at a heating rate of 10°C / min, and keep it for 2h to obtain TiO 2 Nanorod and...
