摘要

采用沉积沉淀法制备了一系列碳纳米管改性的Au/CeO2催化剂，以乙醇部分氧化制氢为探针反应，研究了碳纳米管对Au/CeO2催化剂乙醇部分氧化性能的影响，并运用XRD、TPR、BET等方法对催化剂进行了表征。结果表明，碳纳米管的添加提高了Au/CeO2催化剂的比表面积、孔容和吸氧量，催化剂的氢气选择性先随碳纳米管添加量的增加而大幅增加，碳纳米管的添加量达6%～10%时，氢气选择性达到43%。进一步提高碳纳米管的含量，氢气选择性增加幅度不大。碳纳米管的添加可以有效抑制副产物CO的产生。

Abstract

A series of Au/CeO2 catalysts modified by carbon nanotubes (CNTs) were prepared by deposition-precipitation method.Their catalytic activity and selectivity were investigated by ethanol partial oxidation reaction.XRD

TPR and BET techniques were carried out to characterize the physical and chemical properties of catalysts.The results showed that the addition of CNTs could increase the surface areas and pore volume of Au/CeO2catalyst.Oxygen adsorption capacity of Au/CNTs-CeO2 catalysts

as well as selectivity in hydrogen increased with the increase of CNTs content.Selectivity in hydrogen over Au/CNTs-CeO2 catalysts reached to maximum of 43% when the amount of CNTs is in the range of 6%—10%.Further increasing CNTs content

however

could not increase the selectivity in hydrogen.On the whole

the optimum content of CNTs on Au/CNTs-CeO2 catalysts is about 10%.It was noteworthy that adding carbon nanotubes could effectively inhibit the production of CO.
