A process for producing a bimodal material or a material that contains essentially only mesopores involves heating an inorganic oxide in the presence of material that bonds to the inorganic oxide by hydrogen bonding.Type: GrantFiled: September 7, 1999Date of Patent: March 19, 2002Assignee: ABB Lummus Global Inc.Inventors: Zhiping Shan, Thomas Maschmeyer, Jacobus C. (Cornelis) Jansen

Patent number: 6193943Abstract: A neutral templating route to mesoporous molecular sieves based on H-bonding and self-assembly between neutral primary amine or diamine surfactants (S°) and neutral inorganic precursors (I°) has been used to prepare hexagonal and lamellar mesoporous silicas with site isolated transition metal centers. This templating approach allows for the preparation of hexagonal or hexagonal-like mesoporous oxidation catalysts with large framework wall thickness of at least about 17 Å, small elementary particle size (≦400 Å), and unique combinations of framework-confined mesopores and textural mesopores while at the same time providing for facile recovery of the neutral template by simple solvent extraction.Type: GrantFiled: February 11, 1997Date of Patent: February 27, 2001Assignee: Board of Trustees operating Michigan State UniversityInventors: Thomas J. Pinnavaia, Peter T. Tanev, Wenzhong Zhang, Jialiang Wang, Malama Chibwe
