Investigations of the pore expansion in mesoporous silica in the presence of n-alkanes suggest a cooperative organization of the surfactant and alkane molecules, involving additivity of chain lengths.

A hexagonal mesoporous phase based on SnO2 is synthesized for the first time by using an anionic surfactant; hexagonal phases of TiO2 are prepared with neutral amine surfactants.

The chain length of the surfactant and the solvent composition are two of the factors that determine whether the lamellar or the hexagonal form of mesoporous SiO2 (or ZrO2) is formed by the neutral amine route; a ...
