Embodiment 1
[0022] Put 12 grams of commercial nano-titanium dioxide P25 powder produced by Germany Degussa company into a mortar and grind, and add 4 ml of isopropanol solution containing 10% acetylacetone drop by drop, then add 10 ml of water drop by drop to continue grinding, and mix 0.2 ml Triton X-100 was added to the suspension to prepare a concentration of 54.54% TiO 2 Sol.
[0023] Use the pulling method to coat a 150 μm diameter, 60-mesh titanium metal mesh with a 15 μm thick titanium oxide film at a pulling speed of 10 mm per second, and reserve about 0.3 cm of the titanium metal mesh as a conductive electrode. Heat treatment for 30 minutes.
[0024] Put the coated titanium metal mesh into the 3×10 -5 mol / L N719 ruthenium organic dye ethanol solution, heated to 80°C and soaked for 3 hours, took it out, cleaned it with ethanol, and stored it in a dry and light-proof environment.
[0025] Immerse the titanium metal sheet in the solution containing 5mmol / L H by pulling method 2 ...
Embodiment 2
[0030] Mix 125mL of isopropyl titanate and 20mL of isopropanol evenly, put it into a separatory funnel, add dropwise to 750mL of deionized water containing 5.3mL of 70% nitric acid within ten minutes and stir vigorously. Continue to stir for 8 hours to form transparent nano-TiO 2 colloid solution, and then put it into a high-temperature and high-pressure reactor at a temperature of 200 ° C for 12 hours to react at a constant temperature, and the prepared nano-TiO 2 The sol was concentrated by rotary evaporation to a concentration of 45% TiO 2 Sol.
[0031] A 100 μm-diameter, 100-mesh nickel metal mesh with a thickness of 10 μm was used for a titanium oxide film by screen printing, and a nickel metal mesh of about 0.3 cm was reserved as a conductive electrode, and heat treated at 500° C. for 1 hour.
