Highly ordered mesoporous silicas synthesis using deca(oxyethylene) oleyl ether as surfactant : variation of the weight percentage of surfactant and incorporation of transition metal cations

摘要

The synthesis of highly ordered mesoporous silicas using nonionic C18-1EO10 surfactanthas been made by varying the surfactant weight percentage (SWP) and by incorporation oftransition metal ions in the gel. The variation of the micellar solution composition leads to reorganization of the phase diagram of micelles and the formation of highly organizedhexagonal CMI-3 materials. The role of transition metal cations added during the gelpreparation on the formation of hexagonally ordered CMI-4 silicas is discussed.
