| Abstract: Using Ti0.5Zr0.5O2(TZ) as carrier, the CuO/TZ catalysts were prepared by impregnation method with Cu(NO3)2 as active component, their activities were investigated by using a microreactor-GC NO+CO reaction system, TPR, TG-DTA, XRD and NO-TPD. Experimental results showed that the fine crystallite of CuO on TZ played an important role in NO+CO reaction besides the highly dispersed Cu species, and crystalline ZrTiO4 enhanced the activities of catalysts. NO-TPD analysis inferred that the high temperature adsorption site was probably Cu2+ and low temperature adsorption site was Cu0. |
