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.
