Claim 7:
8. A process for preparation of a photocatalyst thin film device as claimed in claim 1, the process comprising:
loading 1 wt % of a co-catalyst on titania to prepare a photocatalyst composite, wherein the co-catalyst comprises a noble metal, a transition metal, or a metal oxide;
uniformly dispersing the photocatalyst composite in an aqueous alcohol substrate to obtain a catalyst dispersion;
placing the catalyst dispersion on a support to form the photocatalyst thin film device, wherein the support is selected from a glass plate, glass vessels, glass containers, an indium tin oxide (ITO) glass plate, and a fluorine-doped tin oxide (FTO) glass plate, a silicon wafer or steel; and
wherein a ratio of a weight of titania, in mg, to an area of the film, in cm2, is in a range of 0.1 to 4.
