Abstract
A photocatalytically active composition is prepared using high energy mixing. The composition comprises coating carrier material particles with photocatalytically active particles. The coating is performed in the presence of a hydraulic medium. The composition is used in preparation of materials or structures for maintaining a clean surface based on self cleaning property of such a structure.

A photocatalytically active composition comprising carrier material particles coated with photocatalytically active particles, in the presence of a hydraulic medium.
A method for producing a photocatalytically active composition comprising carrier material particles coated with photocatalytically active particles in the presence of a hydraulic medium, comprising introducing said photocatalytically active particles, said carrier material particles, and said hydraulic medium, into a mixing apparatus, and mixing the introduced components dry with a high shear rate or high energy, and collecting the resulting photocatalytically active composition.
