【Abstract】 A series of Cu Mn Ce Zr catalysts were prepared by co precipitation in this study. The activities of catalysts for the moval effect of benzene were evaluated by a normal pressure gas flowing instrument. According to the breakthrough curve and XRD spectrum, the surface characteristics of catalysts were analysed. The result shows that CeO 2 and ZrO 2 can improve the catalytic activities of Cu Mn O catalysts.更多还原
