A TiOphotocatalytic 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 TiO, TiO, and TiO*HO, 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 TiO(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.

Photocatalytic particle comprising TiO2 and its manufacture

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, wherein at least 50 wt % 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. 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 anti-pollution surfaces to be produced also on decorative surfaces. The TiO-comprising layer is thin and easily applied in the production line.

Catalytic substrate surface

The present invention concerns a process for producing carbon nanotubes or other carbon nanostructures, e.g. cones. The process comprising evaporating/decomposing a carbon containing material in a voluminous thermal plasma generated by rotating an electric arc using an externally applied magnetic field, and condensing said evaporated/decomposed carbon containing material on surfaces or on particles in a gas flow. A reactor for performing the process is also described.
