Abstract: The present invention relates to a photocatalytic concrete product and a method to produce a photocatalytic concrete product. In first aspect the invention relates to method of producing photocatalytic concrete product, said concrete product being photocatalytic by containing nano sized photocatalytic particles embedded in an section including a first surface, said first surface forming an exterior surface when the photocatalytic concrete product is used as cover/lining. The method comprises: providing a not-yet-set concrete product having a first surface, applying a dispersion containing nano sized photocatalytic particles, such as titanium dioxide nanoparticles a solvent including a humectant onto said first surface of the not-yet-set concrete product.

Abstract: A coated wood product, comprising a barrier layer and a photocatalytic layer and a method for producing such a coated wood product.

Abstract: A method is disclosed of producing stable nanosized colloidal suspensions of particles with limited crystallinity loss, products thereof, use of the products and an apparatus for the method. In particular the present invention relates to a wet milling method with small beads wherein the size of the final particles in suspension are stabilized in the nanorange (D50<75 nm) and at the same time the particles substantially maintain the crystallinity.
