摘要
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.
