Embodiment 1
[0024] Step 1: Preparation of TiO 2 porous membrane
[0025] 0.10mol L -1 100 mL of the solution, wherein the molar ratio of diethanolamine to butyl titanate is 1:1; then add deionized water with a volume ratio of 0.05:1 to butyl titanate, and at the same time add 30 mg of polystyrene microspheres with a diameter of 100 nm , and then stirred at 38°C for 3.0h to prepare TiO containing polystyrene microsphere template 2 Sol.
[0026] Immerse the clean conductive glass into the TiO containing polystyrene microsphere template agent in step one (1) with a speed of 10cm / min 2 In the sol, place it for 10s, and then transfer the conductive glass from the TiO containing polystyrene microsphere template at a rate of 10cm / min 2 The sol was extracted and dried at 90°C for 2.0h. Repeat the above operation 4 times, and finally raise the temperature of the conductive glass coated with sol to 400°C at 1°C / min, keep it for 3.0h, then raise the temperature to 500°C at 3°C / min, keep it for ...
Embodiment 2
[0031] Step 1: Preparation of TiO 2 porous membrane
[0032] 0.20mol L -1 100 mL of the solution, wherein the molar ratio of diethanolamine to butyl titanate is 1:1; then add deionized water with a volume ratio of 0.05:1 to butyl titanate, and at the same time add 20 mg of polystyrene microspheres with a diameter of 200 nm , and then stirred at 42°C for 2.0h to prepare TiO containing polystyrene microsphere template 2 Sol.
[0033] Immerse the clean conductive glass into the TiO containing polystyrene microsphere template agent in step one (1) with a speed of 12cm / min 2 In the sol, place it for 20s, and then transfer the conductive glass from the TiO containing polystyrene microsphere template at a rate of 12cm / min 2 The sol was extracted and dried at 95°C for 1.0h. Repeat the above operation 6 times, and finally raise the temperature of the conductive glass coated with sol to 400°C at 2°C / min, keep it for 3.0h, then raise the temperature to 520°C at 4°C / min, keep it for ...
