Photocatalytic Substrate Active Under a Visible Light
First Claim
1. A substrate with a mechanically strong and durable coating allowing handling by a user, characterized in that the coating comprises, in intimate association, a photocatalytic first compound and a second compound having a bandgap, between the upper level of its valence band and the lower level of its conduction band, corresponding to a wavelength in the visible range.

Abstract
The invention relates to a substrate provided with a mechanically resistant, long-lasting coating, and suitable for being handled by a user. Said substrate is characterised in that the coating comprises a first photocatalytic compound which is intimately associated with a second compound containing an energy jump between the upper level of the valence band thereof and the lower level of the conductive band thereof, corresponding to a wavelength in the visible field. The invention also relates to a glazing comprising said substrate, to the applications of the inventive substrate, and to the methods for the production thereof.
