摘　　要：通过简单的离子交换法制备出蒙脱土(MMT)负载Cu+催化剂,采用X射线衍射,X射线光电子能谱,扫描电子显微镜和X射线能量色散谱等技术对催化剂样品进行了表征.结果表明,Cu+已经成功的插入到蒙脱土层间.在芳基氯或芳基溴与含氮杂环化合物的N-芳基化反应中,催化剂显示出高的催化活性,且可通过简单的过滤分离出该催化剂,重复使用4次其活性无明显降低.Montmorillonite-supported copper （Ⅰ） catalyst has been prepared by a simple ion exchange method.The resulting catalyst was characterized by X-ray diffraction,X-ray photoelectron spectroscopy,scanning electron microscopy,and energy dispersive X-ray spectrometry,with results showing that Cu＋ had been successfully intercalated into the interlayer of Montmorillonite.The catalyst showed high levels of activity towards the N-arylation of nitrogen heterocycles with aryl chlorides or bromides.Furthermore,the catalyst could be reused up to four times without any significant loss in activity.
