Abstract
A simple, one-step method for producing a homogenous CeO2—TiO2 composite thin film using aerosol-assisted chemical vapor deposition (“CVD”) of a solution containing triacetatocerium (III) and tetra isopropoxytitanium (IV) on a fluorine-doped tin oxide (“FTO”) substrate at a temperature ranging from about 500 to about 650° C. Methods for using the film produced by this method.
Claims16
A homogenous CeO2-TiO2 composite thin film, comprising
- uniformly dispersed crystalline CeO2 and TiO2 phases, and
- mesoporous or smooth microspheres comprising CeO2 and/or TiO2 having an average diameter ranging from about 0.8 to 2.0 μm,
- wherein said thin film has a thickness of no more than 5 μm.
