Patent ID: 11958044
Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCH
Field: Chemical engineering (Chemistry)
Classification: CPC B  C  Y | IPC B  C

Claim 0:
1. A photocatalyst thin film device comprising;
a) a titania photocatalyst film in a form of a composite;
b) a support or glass vessels on which the titania photocatalyst film is deposited, 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
c) an aqueous alcohol substrate;
wherein the composite comprises the titania photocatalyst and a co-catalyst, wherein the co-catalyst is selected from the group consisting of a noble metal, a transition metal, a metal oxide and a combination thereof; and wherein a ratio of a weight of the titania, in mg, to an area of the film, in cm2, is in a range of 0.1 to 4;
wherein the photocatalyst thin film device is configured to generate hydrogen and alcohol oxygenated products by splitting water in direct sunlight.
