Abstract
Hexagonal microporous phases of SiO 2 and AlPO 4 with pore sizes in the range intermediate between traditional microporous and mesoporous materials have been prepared, by making use of supramolecular organization of short-chain amine (n-C 6H 12NH 2) template molecules. The pore diameters are around 1.4 nm in both cases. The hexagonal microporous phase of AlPO 4 is formed only in the presence of fluoride ions. The surface area of SiO 2 after removal of the template is 800 m 2 g −1. In the case of AlPO 4, the surface area is 190 m 2 g −1 after removal of 60% of the template.
