Abstract (en)

[origin: WO2014167231A2] The present invention relates to a method for depositing a photocatalytic coating onto a substrate, including the following steps: a) providing an aqueous and/or alcoholic solution of nanoparticles of a semiconductor material; b) providing a sol in an aqueous and/or alcoholic solution of a hydrolysed organosilane; c) mixing the suspension and the sol and proceeding with the deposit of the resulting mixture onto the substrate to be coated; d) performing a drying operation; e) and optionally illuminating the coating obtained after drying at at least one wavelength leading to the activation of the semiconductor material, such as to remove at least 3% of the organic groups initially present in the coating and bonded to the silicon atoms by Si-C bond. The invention also relates to coatings having photocatalytic properties, to materials — in particular textiles — covered with such a coating and to the use of such coatings and materials for photocatalysis.
