Résumé

The present work deals with a mechanistic study of mesoporous materials (SiO2, ZrO2 and TiO2) formation. A series of polyoxyethylene alkyl ether surfactants such as C13(EO)n (n = 6, 12, 18), C16(EO)10 and C18(EO) 10 have been used to prepare nanostructured mesoporous SiO 2, TiO2 and ZrO2. In the case of silica mesoporous materials, we have correlated the structural characteristics of the recovered mesoporous molecular sieves with the VH/VL ratio of the template. The present research is expected to enlarge the amount of available informations on the possible synthesis mechanisms of mesoporous materials.
