以纤维状高比表面积高岭土（APT）为载体，采用X射线衍射、扫描电镜、透射电镜、N2吸附分析和X射线光电子能谱等手段对CuO/APT催化剂的织构和结构进行了表征。考察了CuO/APT催化剂对CO低温氧化反应的催化性能，结果表明，CuO/APT催化剂的催化活性与文献报道的金属氧化物负载CuO催化剂相当。由于APT粘土具有独特的性质和廉价易得的特点，在低温CO氧化等多种催化反应中具有广阔的应用前景。(C)2008 Elsevier B. V.保留所有权利。
Fiber-like high-surface-area attapulgite (APT) clay was used as a support of CuO particles, and the textural and structural properties of the prepared CuO/APT catalysts were characterized by X-ray diffraction, scanning and transmission electron microscopy, N-2 sorption analysis and X-ray photoelectron spectroscopy. The catalytic behavior of the prepared CuO/APT catalysts for low-temperature CO oxidation was investigated, indicating interesting catalytic activity that comparable to the previously reported metal oxide supported CuO catalysts. Due to the unique property and the feature of much low cost and easy availability, the use of APT clay renders a great promise to be the catalyst support for the applications in various catalytic reactions including the low-temperature CO Oxidation.
