摘要/Abstract

摘要：

以SnO₂为载体, 采用沉积沉淀法(DP)、共沉淀法(CP)和浸渍法(IM)制备了金负载Au/SnO₂催化剂, 同时采用沉积沉淀法制备了M-Au/SnO₂(M=Pd, Pt)双金属负载催化剂. 通过X射线衍射(XRD)、BET比表面积测定、透射电镜(TEM)和X射线光电子能谱(XPS)等技术对样品进行表征, 并测定其对CO的催化活性. 结果表明: 与CP法和IM 法相比, DP法制备的Au/SnO₂-DP 催化剂, Au 颗粒(<5 nm)较小, 分布均匀; Au/SnO₂-DP 中的Au 是以金属态Au0存在, 而Au/SnO₂-CP 和Au/SnO₂-IM 中, 金以Au⁰和Au³⁺的混合价态存在, 在Au/SnO₂-DP和M-Au/SnO₂中的Au、Pt、Pd和SnO₂之间存在相互作用; Au/SnO₂-DP 催化性能明显优于Au/SnO₂-CP 和Au/SnO₂-IM. Au与Pt 和Pd的双金属复合催化剂催化活性明显提高. 不同方法制备Au/SnO₂催化活性的差别主要是由于Au颗粒大小和Au氧化态的不同而产生. 而M-Au/SnO₂活性提高, 可能是由于Au与Pt 和Pd之间的相互作用.

Abstract:

Au/SnO₂ catalysts were prepared by deposition-precipitation (DP), co-precipitation (CP) and typical wet impregnation methods (IM). M(M=Pt, Pd)-promoted Au/SnO₂ catalysts were prepared by the DP method. The samples were characterized by X-ray diffraction (XRD), Brunaner-Emmett-Teller (BET) adsorption, transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) techniques. The results showed that compared with CP and IM, the DP method led to a fairly uniform dispersion of gold nanoparticles with diameters less than 5 nm and larger specific surfaces for the Au/ SnO₂ catalyst. The Au in Au/SnO₂-DP was metallic (Au⁰) while in Au/SnO₂-CP and Au/SnO₂-IM the Au consisted of a mixture of Au⁰ and Au³⁺. The oxidation of carbon monoxide over the Au/SnO₂-DP and Mpromoted Au/SnO₂-DP catalysts were investigated. We observed that the Pd- or Pt-doping of Au/SnO₂-DP resulted in a significant increase in performance. We conclude that the different activities of the Au/SnO₂ catalysts that were prepared using different preparation methods may be attributed to the size of the Au particles and the states of gold. A remarkable improvement in catalytic activity because of Pd or Pt doping was associated with strong interactions between Pd or Pt and Au.
