Patent ID: 7081428

Claim:
A catalytic body for heterogeneous photocatalytic oxidative degradation of organic material comprising an organic polymer with a polymer backbone which forms a polymeric carrier for the catalytic body; a surface facing towards an environment of use, a carboxylic acid derivative having a β-carbon atom and selected from the group consisting of a carboxylic acid, a carboxylic ester, a carboxylic anhydride and an acyl halogenide, being connected by said β-carbon atom contained therein to a carbon atom of said polymer backbone; and a metal cation(s)-containing photooxidation catalyst; wherein the photooxidation catalyst is bonded to carboxylate moieties COO − protruding from said surface and being obtained from said carboxylic acid derivative, which bond to metal cation(s) contained in the photooxidation catalyst.
