Research output: Contribution to journalArticle


Various nanoparticle catalysts were prepared for CO oxidation using the Laser Vaporization Controlled Condensation method. The effects of the nanoparticle supports of SiO2, Al2O3, TiO2), ZrO2, and CeO2 on the activity of the Au nanoparticle catalyst were studied. The Au/CeO2 system showed a great promise for the efficient low temperature CO oxidation. This was directly related to the unique redox properties and high oxygen storage capacity of CeO2. Comparison between the nanoparticle catalysts prepared with chemical methods is presented. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
