The photocatalyst based on a composite WO 3 —SiC/TiO 2 semiconductor and subjected to radiation whose wavelength is at least partly less than 400 nm gives photocatalytic oxidation of volatile organic compounds and leads to their total mineralisation into CO 2 and H 2 O. The process for the photocatalytic purification of industrial, agricultural or domestic gaseous effluent may be conducted at room pressure and temperature. Its conversion rate is high and stable. |
