采用水热法制备了Zr-Ce-SBA-15(ZCS)介孔材料,并以它为载体,通过浸渍法制备了不同Cu/Mn比和Cu-Mn含量的Cu-Mn/ZCS催化剂.采用N2吸附-脱附、透射电镜、扫描电镜、X射线衍射和X射线光电子能谱(XPS)等手段对催化剂进行了表征,并在微型固定床反应器上评价了催化剂催化甲苯燃烧性能.结果表明,Cu-Mn/ZCS催化剂具有六方板状形貌和高度有序的短孔道介孔结构(孔道长0.4～0.5 μm).20%Cu-Mn/ZCS催化剂的比表面积、孔体积和孔径分别为296m2/g,0.42cm3/g和6.4nm.与长孔道的20%Cu-Mn/SBA-15催化剂(孔道长 1～2μm)相比,20%Cu-Mn/ZCS催化剂上甲苯燃烧反应的T95(转化率达95%以上的反应温度)从284℃降至270℃,表明短孔道Cu-Mn/ZCS催化剂具有更高的催化活性.
