Abstract
A method for preparing an amorphous metal oxide film is provided. The method comprises providing an aqueous composition comprising a metal fluorine compound; and contacting a substrate with the aqueous composition at a temperature of less than about 100° C. to obtain said amorphous metal oxide film on the substrate. An amorphous metal oxide film, and use of the amorphous metal oxide film in various applications are also provided.

A method for preparing an amorphous metal oxide film which is superhydrophilic as-grown without requiring activation by UV excitation, the method comprising:
- a) providing an aqueous composition comprising a metal fluorine compound;
- and
- b) contacting a substrate with the aqueous composition at a temperature of less than about 100° C. and for a suitable time period to form metal oxide islands on the substrate, wherein the metal oxide islands are spaced apart from each other to form spacings between the metal oxide islands, and the spacings between the metal oxide islands form mesopores in the amorphous metal oxide film.
