【摘要】 研究了ＺｒＯ２或Ａｌ２Ｏ３负载Ｍｎ－Ｃｕ－Ｏ体系催化剂ＣＯ催化氧化活性，以及物相结构、表面氧性能与活性的关系．结果表明，锆基催化剂的氧化活性明显优于铝基催化剂，起燃温度Ｔ５０低达５０℃．ＺｒＯ２载体有利于活性组份形成高活性物相，并促进表面吸附氧的脱附，表现出催化剂表面吸附氧的脱附温度高低次序与其氧化活性有一致的对应关系．更多还原

【Abstract】 The catalysts of ZrO 2 and Al 2O 3 supported Mn Cu O used for oxidation of CO at low temperature were studied. Factors affecting the catalytic activity such as crystal structure and surface oxygen property were examined by XRD and TPD MS techniques. The results showed that ZrO 2 support would promote the formation of CuMn 2O 4, the desorption of surface absorbed oxygen over Mn Cu O, and increase the amount of surface absorbed oxygen. Thus it increased the activities of CO oxdation.更多还原
