| Compared with the Cu/ZSM-5, additives Zr, Ce additions significantly altered the catalyst on the desorption behavior of oxygen so that oxygen desorption bee strength and increase the size of a lot of copper ions is also lower the temperature of oxygen desorption 20K. Can be seen Zr, Ce additions to enhance the catalyst oxygen storage capacity, improve its oxygen desorption at low temperature performance. |
