Photocatalytic active coatings obtained at low temperature
Process for obtaining a coating with photocatalytic properties based on titanium dioxide comprises a sol-gel deposition stage of a dispersion of a titanium dioxide precursor followed by an anatase crystallization by thermal treatment under pressure at a temperature lower than 140 degrees C and at saturation vapor pressure of a mixture of water and an organic solvent. <??>An Independent claim is also included for the coated substrate obtained.
