摘　　要：采用菁青石陶瓷蜂窝做载体,用浸渍法制备了Pt-Pd-Rh负载型催化剂。试验结果表明,老化前,起燃温度为320～325℃;转化率可达CO:97.9%,THC:92.7%,NOX:99.1%。The cordierite ceramic honeycombs were made into carrier of the catalysts,and the PtPbRh supported catalysts were prepared by the impregnation method The testing results indicate that the igniting temperature is 320～325℃ and the conversion rate of CO 979%, THC 927% and NOX 991% before aging
