Abstract

Both the catalytic oxidation of CO and the development of catalysts for oxidation of CO at low temperature are very significant for basic research and industrial applications.Pt/CeO₂ catalysts that are prepared via atomic layer deposition method can efficiently drop the temperature at which CO can be oxidized.The catalytic performance of Pt/CeO₂ can be improved effectively by tuning the cycles of Pt ALD and pretreatment conditions.Especially, the temperature for oxidation of CO can be as low as 60℃ after the catalysts are pretreated in a hydrogen atmosphere.The catalysts are characterized by XRD, ICP, TEM, XPS and H₂-TPR.It is found that Pt has been highly dispersed on the surface of CeO₂ nanorods, and there are strong interactions between Pt and CeO₂.After pretreated by hydrogen, the adsorption of CO by Pt can be enhanced, which can improve its catalytic performance for oxidation of CO.
