  • Substrate with a photocatalytic coating
    Patent number: 6720066
    Abstract: The present invention is directed to a process for obtaining a substrate provided with a coating having photocatalytic properties, wherein the coating includes crystallized particles of an oxide of a metal A having photocatalytic properties. The crystallized particles are incorporated into the coating using a mineral binder comprising at least one oxide of a metal B also having photocatalytic properties in the crystallized state. The coating optionally includes at least oxide of a metal M devoid of photocatalytic properties and/or at least one silicon compound of the silicon oxide SiO2 type. The coating is deposited from liquid-phase dispersions containing the crystallized particles of the oxide of metal A and at least one precursor compound for the oxide of metal B of the binder and optionally a precursor compound for the oxide of metal M and for the Si compound, in a relative proportion A/(B+M+Si) by weight of the metals and Si ranging between 60/40 and 40/60.
    Type: Grant
