Abstract
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.
Claims16
A quasi crystalline inorganic oxide composition having framework-confined mesopores prepared by a method which comprises reacting a neutral amine template and a neutral inorganic oxide precursor wherein the template is dissolved in a solution of water and a miscible organic solvent, containing a larger volume of either the miscible organic solvent or the water, aging of the precipitate and removal of at least some of the template and the aqueous solution to form the quasi crystalline composition which has regular wormhole shaped channels.
