SUBSTRATE WITH PHOTOCATALYTIC COATING

摘要

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 semiconducting metal oxide. AN Independent claim is also included for: (1) a process of production of the substrate by deposition of the photocatalytic coating with thermal decomposition of at least one organometallic and metallic halide precursor, such as powder, liquid or gaseous pyrolysis; and (2) A process of production of the substrate by deposition of the photocatalytic coating by vacuum deposition, especially cathodic pulverization.
