Abstract
In this study, Nano-TiO2films are incorporated with heavy metal Pt by the Sol-Gel Dip-Coating (SGDC) method to change their photo-catalytic properties. The Pt and Pt/TiO2sol is prepared first, then it was used for coating on the ITO by the Dip-Coating method; finally, through calcination under the high temperature, the desired Pt and Pt/TiO2film can be obtained. The film structure was tested by the photoelectric test, XRD and AFM. Results showed that the best preparation conditions is identified as 10ml of Tetrabutyltitanate, 20ml of Anhydrous ethanol and 3ml of Tri-ethanolamine, with a 450°C of calcination temperature lasting for 3h; 3 layers of coating is also suggested with the Pt content being 0.30mol %.
