| 摘 要： | 利用XRD,BET和H2-TPR等方法对制备的负载型催化剂Pt/CZ进行了表征。采用浆料球磨涂覆工艺制备了含铈锆固溶体的三效催化剂,并在模拟乙醇汽油车尾气条件下对其催化性能进行了评价。结果表明,三效催化剂有良好的CO,HC,NOx和CH3CHO同时净化的三效性能和低的起燃活性,有较高的活性,还有良好的抗高温性能。气氛中加入SO2后降低了催化剂活性。 |

| Abstract: | The prepared Pt/CZ catalysts were characterized with XRD,BET and H2-TPR methods.The three-way catalyst including ceria-zirconia solid solution was prepared with the paste ball mill coating technology and its catalytic performance was evaluated under the conditions of simulating ethanol gasoline engine exhaust.The results show that the catalyst show the excellent low temperature performances,the three-way catalytic activity for CO,HC,NOx and aldehyde and the high-temperature resistance.It is found for furthe... |
