【Abstract】 In this paper,the influences of translation metals on Pt Rh Pd/Al 2O 3 catalyst performance were studied,The promoters effects on catalysts were discussed by means of X ray diffraction(XRD),temperature programmed desorption(TPD)and temperature programmed reduction(TPR).The results show that there are synergistic effcects between translation metals and noble metals,which can enhance the activity of catalysts.更多还原
