Abstract Gold nanoparticles were sol–gel‐entrapped in the mesoporous structure of organically modified silica matrices, and the resulting Silia Cat Au materials were tested as oxidation catalysts in the model reaction of 1‐phenylethanol with hydrogen peroxide. The new materials were characterized by electronic microscopy, IR spectroscopy, and cryogenic N 2 sorption. The results point to conclusions of general validity that allow us to advance towards the practical use of supported gold nanoparticles in a number of applications.
