Ordered benzene–silica hybrids with molecular-scale periodicity in the walls and different mesopore sizes
摘要：
Mesoporous benzene–silica hybrid materials have been obtainedviasurfactant-mediated synthesis using alkyltrimethylammonium surfactants with alkyl chain lengths from 14 to 18. By combining N2adsorption–desorption experiments and powder X-ray diffraction PXRD analysis we showed that these samples exhibited mesopore sizes in the range 3.2 to 3.9 nm and that the molecular-scale periodicity in the walls of these materials is maintained. Transmission electron microscopy TEM, solid state nuclear magnetic resonance NMR and thermogravimetric analyses TGA have also been used to characterise the structure and stability of the samples.
