14N NMR study of surfactant mesophases in the synthesis of mesoporous silicates

Abstract

Surfactant mesophase formation during the synthesis of M41S, the mesoporous material, has been studied using ¹⁴N nuclear magnetic resonance spectroscopy. Siliceous gels producing M41S materials displaying hexagonal and lamellar powder X-ray diffraction patterns have been observed to contain hexagonal mesophases which revert to an isotropic solution after heating while X-ray diffraction shows the silicate to be ordered.
