The present invention relates to a mixture, comprising at least one thermoplastic polymer as component (A) and at least one photocatalytically active particle, comprising a non-porous core comprising at least one metal oxide or semimetal oxide with a diameter of from 0.1 nm to 1 &#x3bc;m, and, at least to some extent surrounding the core, at least one porous outer layer comprising at least one further metal oxide or further semimetal oxide with an average layer thickness of from 0.1 to 10 nm, as component (B), to a process for the production of this mixture according to any of claimsto, via mixing of components (A) and (B), to the use of the mixture as photocatalytically active surface, to moldings, comprising this mixture, and to the use of this mixture for the production of moldings.

Self-cleaning polymers

The present invention relates to a reactor for the photocatalytic treatment of liquid or gaseous streams, which reactor comprises a tube through which the stream to be treated flows, wherein, in the tube, there are arranged at least one light source, at least one flat means Mprovided with at least one photocatalytically active material and at least one flat means Mreflecting the light radiation radiated by the at least one light source, wherein the reflecting surface of the at least one means Mand the inner wall of the tube are at an angle greater than or equal to 0&#xb0;, in such a manner that the light exiting from the light source is reflected by the at least one means Monto the photocatalytically active material, and to a method for the photocatalytic treatment of liquid or gaseous streams by irradiation with light in the reactor according to the invention.
