Porous Aluminum Oxide Materials Prepared by Non-Ionic Surfactant Assembly Route

Number: 6,027,706
Year: 2000
Patent Status: Issued
Authors: Pinnavaia, T.J., W. Zhang

Semi-crystalline alumina compositions with framework mesopores are disclosed. The compositions are assembled from inorganic aluminum precursors and nonionic polyethylene oxide surfactants. The new assembly pathway introduces several new concepts to alumina mesostructure synthesis. The application of low-cost, non-toxic and biodegradable surfactants and low cost aluminum reagents as alumina precursors which are inorganic and low solution reaction temperatures, introduces efficient and environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the surfactant can be achieved through solvent extraction where the solvent may be water or ethanol or by calcination.
