Patent number: 8003567Abstract: The present teachings are directed toward hexagonally patterned porous titania synthesized from a titanium isopropoxide precursor using a viscous template of surface-active agents separating nanoscopic bicontinuous channels of water and isooctane. Subsequent catalyst metal salt reduction in the aqueous nanochannels deposits well-separated catalyst metal nanoparticles on the pore surfaces. These nanocomposites exhibit significantly higher carbon monoxide oxidation efficiency than that obtained with known supports with higher specific surface area; efficiency is believed to be due to decreased mass transfer resistance provided the presently disclosed support material.Type: GrantFiled: August 17, 2009Date of Patent: August 23, 2011Assignees: Honda Motor Co., Ltd., The Administrators of the Tulane Educational Fund, Rhode Island Board of Governors for Higher Education, Rensselaer Polytechnic InstituteInventors: Christopher Brooks, Arijit Bose, Jayashri Sarkar, Ganapathiraman Ramanath, Vijay T.

Patent number: 7985707Abstract: An alkali metal-containing catalyst is prepared by providing a catalyst-containing component which contains an alkali metal and another catalyst metal, for example, transition and platinum group metals, and contacting the catalyst-containing component with a binder agent in the presence of a non-aqueous, non-polar component to form a mixture. The mixture is then applied to a suitable catalyst substrate and calcined at the appropriate temperature to produce the alkali metal-containing catalyst. One preferred alkali metal is sodium, and oxides of silicon, aluminum and zirconium may be used as binder agents.Type: GrantFiled: February 24, 2006Date of Patent: July 26, 2011Assignee: Honda Motor Co., Ltd.Inventors: Christopher J.
