Surface-modified inorganic substrate and method for preparation thereof

The present invention relates to a method for the modification of metal hydroxide and/or metal oxide surfaces of an inorganic matrix with an organometallic reagent for obtaining an organic functionalized matrix suitable for filtration processes. The method involves the direct covalent binding of organic functional groups by allowing a pre-treated matrix to react with organometallic reagents in the present of a suitable solvent. The present invention further relates to an organic functionalized matrix obtainable or obtained by carrying out a method according to the invention. The invention also provides various uses of a surface-modified matrices as described herein in various industrial applications, including for instance in filtration and/or adsorption and/or separation processes, or as support, e.g. for catalyst systems or for enzyme systems.
