| Abstract: | The effect of CuSO4 on the property of catalyst CuO/Al2O3 hasbeen investigated. The TPD-MS results showed that the amount of oxygen adsorbed on the surface of CuSO4-CuO/Al2O3 increased with CuSO4 content in the catalyst and the oxygen desorbed only at temperature above 900 K. TPSR results showed three adsorption sites of NO on the surface of CuO/Al2O3, respectively at 398, 643 and 683 K. The active site at 683 K was for NO decomposition and it was poisoned seriously when there was CuSO4 in the CuO/Al2O3. For CuSO4-CuO/Al2O3 the amount of N2O formed from NO decomposition reduced probably due to the increase of oxygen species in the catalyst. |
