Embodiment 1
[0022] 1. The semiconductor photoanode material adopts TiO with light corrosion resistance and good chemical stability 2 . Using sol / gel+powder method to convert TiO 2 Fixed on conductive glass surface.
[0023] TiO 2 Sol preparation process: Add appropriate amount of concentrated nitric acid to distilled water, and heat to 70°C with a constant temperature water bath. Take a 1:3 isopropanol: butyl titanate solution and mix it evenly, then slowly add it dropwise into distilled water at constant temperature and stir, and continue to stir at constant temperature for 2 hours to obtain TiO-containing 2 27g / L TiO 2 Sol, sealed and stored. See attached for the process figure 1 .
[0024] TiO 2 Slurry preparation process: take appropriate amount of TiO 2 Sol, adding nano-TiO 2 powder (nano TiO 2 TiO in powder press slurry 2 The total amount is 120g / L (calculated to add), grinding and ultrasonic dispersion to obtain TiO 2 slurry.
[0025] TiO 2 Coating preparation proces...
