中文摘要：

用多步接枝法将不对称席夫碱Cu（Ⅱ）配合物Cu（CBP—PHEN—Sal）共价联接到介孔分子筛MCM-41的表面。对得到的材料用XRD、FHR、DR UV-Vis、氮气吸附、元素分析和ICP进行了表征。结果表明，不对称席夫碱Cu（Ⅱ）配合物被成功地固载于MCM-41的孔道中，而且固载后MCM-41的结构特征保持不变。考察了固载催化剂在烯烃液相氧化中的催化活性。以叔丁基过氧化氢为氧化剂，在苯乙烯氧化中，固载催化剂比配合物表现出更高的催化活性。同时，研究了反应条件，例如溶剂、催化剂用量、温度和反应时间对固载催化剂催化性能的影响。

英文摘要：

An unsymmetrical copper（Ⅱ） schiff base complex, Cu（CBP-PHEN-Sal）, was covalently anchored onto the silica surface of MCM-41 by a multi-step grafting method. The resulting material was characterized by XRD, FTIR, DR UV-Vis, nitrogen adsorption, elemental analysis and ICP. The results showed that the unsymmetrical copper（Ⅱ） schiff base complex was immobilized inside the channels of MCM-41 and that textural characteristics of the support were kept intact after the immobilization. The catalytic activity of the immobilized catalyst for the liquid phase oxidation of olefins was tested. The immobilized catalyst showed a higher ctalytic activity compared to the neat complex in the oxidation of styrene with TBHP as the oxidant. The effect of reaction conditions such as solvent, catalyst amount, temperature and reaction time on the catalytic performance was also investigated.
