The invention concerns a substrate provided on at least part of one of its sides with a coating having photocatalytic properties containing photocatalytic titanium oxide, in particular crystallised in the anastase form, in an essentially mineral binder comprising at least a semiconductor metal oxide. The invention also concerns the method for obtaining such a substrate, in particular by thermal decomposition of precursors or by vacuum deposition process.
L'invention a pour objet un substrat muni sur au moins une partie d'au moins une de ses faces d'un revêtement à propriétés photocatalytiques contenant de l'oxyde de titane photocatalytique, notamment cristallisé sous forme anatase, dans un liant essentiellement minéral comprenant au moins un oxyde métallique semi-conducteur. L'invention a aussi pour objet son procédé d'obtention, notamment par décomposition thermique de précurseurs ou par une technique de dépôt sous vide.
