    摘要： There is disclosed a catalytic substrate surface where in the substrate surface comprises particles in the size range 2-500 nm, said particles comprising TiO
    2 , wherein at least 50wt% of the Ti in the particles is leachable in 37% HCl. A method for its manufacture is also provided. One advantage is that the higher fractions of Ti leachable in 37% HCl give a better coating with better adhesion, in particular on objects comprising protonatable acidic oxides, such as SiO
    2 . The higher fraction of Ti leachable in 37% HCl gives better transparency and dispersion stability. The resulting surface exhibits both improved activity and improved adhesion of the particles. There is no color change and/or speckles on the substrate, allowing antipollution surfaces to be produced also on decorative surfaces. The TiO
    2 - comprising layer is thin and easily applied in the production line.

    摘要： A TiO2 photocatalytic particle comprises at least one core with a crystalline anatase structure, a first layer is at least partly surrounding the core, and comprising one from TiO2, TiO(2-x), and TiO2*H2O, said first partly ordered layer comprising parts where molecules are aligned with an imaginary extension of the crystal planes of the core, the first layer is in close contact with a second outer layer, at least partly enclosing the first layer and the core. The second layer comprises one from layered titanium dioxide and titanium dioxide in TiO2 (B)-form, said second layer is partly ordered, and said second layer comprising sheets aligned with crystal planes transversal to the outer surface of said particle. Advantages include that the outer layer of the particles can be modified to be optimized for the particular application which is an advantage for catalysis and other application where the properties of the outermost surface is of importance.
