Three-way catalyst (TWC) is the control of vehicle exhaust pollution one of the most effective means. Ce zirconium solid solution (CZ) because of its good performance was stored oxygen to the extensive use of three-way catalyst. Baptist in the exhaust gas in the process involves a lot of reaction, the reaction between the complex interaction, so the response of the network it is particularly important. This study used sol - gel synthesis of the cerium zirconium solid solution, a volume impregnation load 0.5% of the precious metal Pd, in order to examine the aging treatment on the catalytic activity of the fresh samples in 950 ℃ and 1050 ℃ with 10% H2O An atmosphere of thermal aging water treatment. Major research atmosphere at the different reactions to the CO and C3H8 catalytic activity of the law. By XRD Characterization of the samples crystalline structure and surface patterns, use of BET inspected samples of the surface area catalytic activity.

Three effect catalysts (TWC) is one of present control automobile exhaust pollution most effective methods. Cerium zirconium solid solution (CZ), because it has the good storage oxygen performance widely to utilize to three effect catalysts. In the exhaust macerates in the process to involve to many responses, between each response has the complex mutual influence, therefore appears to reaction network's research especially important. This research used the sol - gelatin law to synthesize the cerium zirconium solid solution, used and so on volume impregnation method load 0.5% precious metal Pd, to examine the aging to process to the catalytic activity influence, separately in 950℃ and 1050℃ carried on water thermosenescence processing to the new sample including in the 10%H2O atmosphere. Mainly has studied when the different response atmosphere to CO and C3H8 catalytic activity influence rule. Has studied the sample crystalling phase structure and the surface contours through the XRD attribute, uses the BET inspection sample the relative surface to the catalytic activity influence. And has conducted the research to the sample storage oxygen performance.
