Abstract： |
The present invention is nanometer titania film and its preparation process, and belongs to low-dimensional nanometer material technology. In the electrochemical deposition process, nanometer titania powder, surfactant, anhydrous ethanol and metal salt as electrolyte are mixed and ultrasonic dispersed to obtain homogeneously dispersed stable suspension. By means of stainless steel or nickel sheet as anode, transparent conducting ITO glass or transparent conducting FTO polymer as depositing cathode, and constant voltage power source, nanometer titania film is deposited on the cathode substrate at room temperature. The deposited film is then heat treated at 400-550 deg.c or microwave treated for 1-3 hr. The process has easy control and low temperature, and the deposited nanometer titania film has flat surface, high porosity, great specific area and low cost. The present invention is suitable for industry production of dye sensitized solar cell film material. |
