Three-way catalyst( TWC)s control one of the most valid meanses in the automobile tail spirit pollution currently.Along with the improvement of the fuel quantity,three effect catalysts of single Pd is cheap with it and efficiently of catalyst activity get the widespread concern.The Ce- Zr is solid to dissolve the body( CZ) because of it goodly keep to put the oxygen function to is made use of to three effect catalysts.This text with dissolve the gum- Gel gum legal system fully the CZ is solid to dissolve the body to carry the body,adoption etc.the physical volume immerses the legal system of Impregnation to have the Pd load to measure for 0.5% catalyst Pd/ Ce- Zr,and carry on the hot and aging processing of water to the fresh sample.Investigating the sample keeps to put the oxygen function,and apply the XRD research sample Crystalline structure mutually structure and the surface appearance,pass the ratio surface of the BET analysis means investigation sample,did the evaluation of the catalyst activity with the TWC.Do the catalyst with the Pd/ Ce- Zr,the usage TWC equipments imitates the automobile tail spirit to constitute,responding the atmosphere in the dissimilarity under( from two dollar mixture to whole hybrid system,imitate the true condition under of the automobile tail spirit) get a CO,HC and the NOx conversion rate data,analyze the competition relation between each reaction and have the initiative in proper order,study the reaction network.
