ZSM-5分子筛负载复合过渡金属催化剂（Cu-Mn/zeolite）兼具分子筛和复合过渡金属的双重优势，在催化燃烧消除VOCs领域具有良好的催化性能。通过超重力技术制备了ZSM-5负载复合过渡金属催化剂，系统地研究了超重力环境下制备的Cu-Mn/ZSM-5催化剂的催化活性，并与传统浸渍法制备的催化剂进行比较。通过BET比表面积测试法、X射线衍射、程序升温还原、扫描电子显微镜和X射线光电子能谱分析等技术对催化剂进行表征，结果表明，超重力法制备的催化剂具有更高的催化活性，活性组分在ZSM-5上均匀分散，且负载量较高。

ZSM-5 molecular sieve supported composite transition metal catalyst (Cu-Mn/ZSM-5) has the dual advantages of molecular sieve and composite transition metal,showing excellent performance in catalytic combustion to eliminate VOCs.ZSM-5 supported composite transition metal catalysts are prepared by high gravity technology.The activity of Cu-Mn/ZSM-5 catalyst prepared by high gravity technology is systematically studied and it is compared with Cu-Mn/ZSM-5 catalyst prepared by traditional impregnation method.The as-prepared catalyst is characterized by BET specific surface area measurement,X-ray diffraction (XRD),hydrogen temperature programmed reduction (H₂-TPR),scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS).It is concluded that higher activity of catalyst can be obtained via high gravity technology than traditional impregnation method.The active components disperse uniformly on ZSM-5 for the catalyst prepared by high gravity method,and showing a high loading amount.
