Patent ID: 7510763

Claim:
A substrate, comprising: a substrate support; and a coating provided on at least part of a surface of the substrate support; wherein: the substrate support comprises an essentially transparent substrate, a ceramic substrate, a glass-ceramic substrate, an architectural material substrate, or a fibrous substrate; the coating has a mesoporous structure and exhibits photocatalytic properties; the coating comprises a coating composition and at least partially crystallized titanium oxide incorporated into the coating composition in the form of perfectly discernible particles; the coating composition differs in composition from the at least partially crystallized titanium oxide; and the substrate is prepared by: preparing a liquid composition comprising at least one precursor of the coating composition, and at least one organic structuring agent; precipitating the at least one precursor around the at least one organic structuring agent; adding the at least partially crystallized titanium oxide to the liquid composition; applying the liquid composition to the at least part of the surface of the substrate support; and removing the organic structuring agent, thereby forming the coating on the substrate.
