Abstract

A technique was developed which utilizes pre-arranged surfactant-salt structures as precursors for microporous and mesoporous framework materials. Transition metal silicates with long-range structural order were syntherized by reacting surfactant salts of niobotungstate clusters with tetraethylorthosilicate to form a salt-gel. Infrared and solid state NMR double resonance spectra indicate that, in addition to linkages between silicate tetrahedra, niobium-oxygen-silicon linkages were formed in this reaction. Removal of the cationic surfactants by acid-extraction resulted in porous structures with surface areas up to 265 m2/g.
