Résumé

Ordered mesoporous silica molecular sieves were obtained using a series of non-ionic Cm(EO)n surfactants. The control of the hexagonal structure was achieved by adding transition metallic cations to the micellar solutions. It has been shown that highly organised CMI-2 and 4 materials could be obtained with C16(EO)10 and C 18(EO)10 whereas disordered wormhole-like mesostructures were reached with C13(EO)6 and C13(EO) 12.
