Polyoxometalates of colloidal size have been immobilized in a silica-matrix via sol-gel synthesis. The resulting (porous) materials exhibit the unique properties of both the polyoxometalates (POMs) and of the host silica. The pocket molded into the silica by the POM-cluster acts as a special nano-dimensional “reaction vessel”, where the POMs can undergo chemical transformations without leaching of the molybdato units.
