| 초록 |
In this study, the characteristics of palladium type catalyst was evaluated with TPR, XRD and propane oxidation test. For fresh palladium type automotive catalyst palladium hydride(PdHx) was observed after the first TPR, and for hydrothemal aged one palladium hydride was founded under the first TPR. The generation and disapperance of palladium hydride were affected by pretretment condition such as oxidation temperature. Reproductionof PdHx did not occur after by disappearance of PdHx by a high thermal treatment above 700℃. Among aged catalysts one with reduction treatment showed the highest activity for propane oxidation. |
