Patent number: 8025861Abstract: Titanium oxide (usually titanium dioxide) catalyst support particles are doped for electronic conductivity and formed with surface area-enhancing pores for use, for example, in electro-catalyzed electrodes on proton exchange membrane electrodes in hydrogen/oxygen fuel cells. Suitable compounds of titanium and a dopant are dispersed with pore-forming particles in a liquid medium. The compounds are deposited as a precipitate or sol on the pore-forming particles and heated to transform the deposit into crystals of dopant-containing titanium dioxide. If the heating has not decomposed the pore-forming particles, they are chemically removed from the, now pore-enhanced, the titanium dioxide particles.Type: GrantFiled: March 3, 2010Date of Patent: September 27, 2011Assignees: GM Global Technology Operations LLC, Administrators of the Tulane Educational FundInventors: Mei Cai, Yunfeng Lu, Zhiwang Wu, Lee Lizhong Feng, Martin S.

Patent number: 7837966Abstract: Ozone and, if necessary, water is added to an exhaust gas, such as air, containing hydrogen- and carbon-containing molecules of a pollutant. The exhaust gas is then continually flowed into one or more oxidizing reaction chamber modules. In the reaction chamber(s) the ozone- and water-containing gas is subjected to intense ultraviolet radiation (wavelength of 254 nm) to promote the formation of hydroxyl radicals to oxidize the pollutant molecules to carbon dioxide and water. The continually discharged gas is analyzed for residual ozone and hydrocarbon content and the analytical data used in feedback control of ozone addition and UV radiation intensity.Type: GrantFiled: February 23, 2005Date of Patent: November 23, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Kenneth B.
