Synthesis of Cr/CexZr1-xO2 and its Performance in Catalytic Oxidation NO

Wei Cai and Qin Zhong

Abstract—Cr/CexZr1-xO2 catalysts were prepared by impregnation method and used for catalytic oxidation of NO. The effects of preparation conditions including the various Ce/Zr of the support, the loading of active component, calcination temperature, and operating conditions as reaction temperature, O2 and NO concentration, gas hour space velocity for catalytic oxidation were investigated. The results showed that 7%Cr/Ce0.14Zr0.86O2 which was calcined at 400 ℃ showed optimal catalytic oxidation activity. And O2 was important for the NO adsorption over the Cr/CexZr1-xO2 catalysts.

Index Terms—Ceria-zirconia solid solution; catalytic oxidation; NO.
