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&deg; C.

Process for the preparation of hybrid mesoporous molecular sieve silicas from amine surfactants

Porous inorganic silica foam compositions are derived from water soluble silicate precursors and swollen non-ionic polymer templates are described. The compositions are useful as catalyst supports and as catalysts in hydrocarbon cracking and organic reactions, among other applications.

Silica foam compositions

A process for the preparation of mesostructured molecular sieve silicas from inorganic silicon precursors and polyoxyethylene oxide based polymers is described. The silicas are stable upon calcination to 600&deg; to 800&deg; C. The silicas are useful in refining processes.

Process for the preparation of molecular sieve silicas

Crystalline inorganic oxide compositions having regular wormhole-like channels are described. The formation of the mesoporous composition is accomplished by hydrogen bonding between a neutral amine template in water and a water miscible organic solvent and a neutral inorganic oxide precursor, wherein there is an excess of an alkanol or water used to dissolve the template. The template can be removed and recycled.
