中文摘要：

以聚甲基丙烯酸甲酯（PMMA）为硬模板制备了一系列具有三维有序大孔（3DOM）结构的CuO-Ce02催化剂，考察了CuO负载量和三维立体结构对CuO-CeO2催化剂c0催化氧化性能的影响．结果表明，催化剂20CuO-CeO2-S的催化活性最好，且明显优于等体积浸渍法制备的催化剂．这可能是由于三维有序大孔结构催化剂中CuO能更好地分散所致．

英文摘要：

Three-dimensionally ordered macroporous CuO-CeO2 catalysts were prepared by using polymethyl methacrylate （ PMMA） as a hardtemplate. The effect of CuO loading and the 3DOM structure on CO oxidation activity were investigated. The results showed that the 20CuO-CeO2-S had the best catalytic activity. Moreover the catalytic activity was better than the catalyst prepared by using incipient-wetness impregnation meth- oil. ihis might be due to the better dispersion of CuO on CuO-CeO2-S catalysts.
