中文摘要：

采用水热合成法,合成了Co/MCM-41,制备了掺杂Co且具有锐钛矿晶型的介孔二氧化钛Co/MTiO2,用N2吸附/脱附,XRD,FI-IR对合成材料进行了表征;结果表明合成的Co/MCM-41和Co/MTiO2为比表面积较高,孔容较大的介孔材料,所掺杂的过渡金属离子为高度分散的.讨论了2种催化剂在氧化对氯甲苯制备对氯苯甲醛的催化活性.

英文摘要：

Cobalt - doped MCM - 41 （ Co/MCM - 41 ） and mesoporous titania （ Co/MTiO2 ） with a crystalline framework synthesized by surfactant templating method. They were characterized by nitrogen adsorption, X - ray diffraction and FT - IR spectroscopy. The results indicated that material has uniform hexagonal channels and transition metals were well dispersed. The catalytic activity oxidation was studied by p - chlorotoluene to p - chlorobenzaldehyde.
