摘要
A photocatalytic system having enhanced photo efficiency/photonic efficacy is provided that includes a thin nucleation material coated on a substrate. The nucleation material enhances lattice matching for a subsequently deposited photocatalytic active material. Such a photocatalytic system may be used as a self-cleaning surface in an application where removal of fingerprints and other residue is desired. In certain aspects, the nucleation material comprises aluminum oxide (Al2O3) and the photocatalytic material comprises an anatase phase of titanium dioxide (TiO2) deposited over the nucleation material. A photocatalytic activity of the system is ≥ about 50% above a comparative photocatalytic activity where the photocatalytic active material is disposed directly on the substrate. Methods of making such photocatalytic systems are also provided.
