Three-way catalyst (TWC) is the control of vehicle exhaust pollution one of the most effective means.With the improvement of the quality of fuel,single-Pd three-way catalyst for its cheap and efficient catalytic activity of universal concern.Ce zirconium solid solution (CZ) because of the good performance of oxygen stored to be used in the three-way catalyst.In this paper,to 0.5 wt% Pd / Ce-Zr as catalyst,simulated automobile exhaust components,in response to different atmosphere (from the binary mixture to full-hybrid system,simulate the real situation of the automobile exhaust) that CO,HC and NOx conversion Rate data to study automobile exhaust components may arise between the response of the competition among the various responses and priorities,study Response Network.Evaluation of the three-way catalyst activity.This article is a catalyst for use by sol - gel method to cerium zirconium atoms than 0.67:0.33 for the preparation,such as volume impregnation load Pd,and fresh water samples were handled by the aging of the three samples.This was also inspected the samples stored oxygen performance and application XRD study sample surface crystalline structure and form,through the means of inspection BET analysis of samples of surface area.
Key words:Three-way catalyst; cerium zirconium solid solution; storage of oxygen; palladium; Response Network
