METHOD FOR FORMING TITANIUM DIOXIDE PHOTOCATALYST THIN FILM ON POLYMER SUPPORT

摘要

PURPOSE: A method for forming titanium dioxide photocatalyst thin film on polymer support is provided, which can prepare thin film at room temperature and decompose nonbiodegradable toxic organic matter such as phenol, coloring compound such as methylene blue and organic matter such as salad oil. CONSTITUTION: The manufacturing method is as follows: (i) prepare antase titanium dioxide nanosol solution by reacting titanium alkoxide, complex forming agent and water in the presence of acid catalyst; (ii) dilute by adding alcohol solution to the prepared titanium dioxide nanosol solution; (iii) washcoat the diluted titanium dioxide nanosol solution on a polymer support; (iv) dry the washcoated thin film at 25-100 deg.C; and (v) repeat the washcoating and drying steps of the washcoated thin film serially.
