A method for preparing an additive comprising TiO 2 particles dispersed on a quasi-layered phyllosilicate type carrier, the dispersion of the carrier in water, acid activation of the carrier, and the addition of TiO 2 particles A method comprising high shear dispersion of a carrier. Water purification and sterilization, pollution gas stream purification, and imparting self-cleaning, biocidal, deodorizing, and / or pollution reducing properties to materials (especially construction materials) in the presence of air and ultraviolet light Use of the TiO 2 particles obtained by the above method as an additive having photocatalytic activity for the purpose. |
