- 論文の詳細を見る
A study was conducted to demonstrate that nanometer-thick titanium dioxide (TiO2) thin films could be prepared by the hydrolysis of titanium potassium oxalate using octadecylamine (ODA) Langmuir-Blodgett (LB) films as templates. The amount of TiO2 generated in the LB film was found to be proportional to the number of deposited ODA layers, which enables precise control of the TiO2 film thickness. After heat treatment of the LB films at 300-600°C, the photocatalytic activities of the resulting TiO2 films were determined from the decomposition of stearic acid cast films when irradiated with UV light for different time periods. Higher photocatalytic activity was observed in TiO2 films heat treated at lower temperatures.
