Abstract
Hybrid mesoporous molecular sieve silica compositions which have intergrown wormhole domains and lamellar or hexagonal domains and prepared from mixtures of water soluble silicate precursors and amine surfactant templates through a neutralization reaction are described. The silica compositions are stable above 600° C.
