| 英文摘要: |
| The structural characterization of the 1 wt% Sr/La2O3-Bi2O3-Ag-YSZ catalytic membrane before and after the reaction of oxidative couping of methane was studied by SEM. The membrane showed well distributed micro-structure. The fusion phenomena was not serious after reaction. During the period of 72 h reaction, the behaviors of the memberane remained unchanged.The consisent results showed that the membrane prepared in the experiment had a long term stability.The type and state of surface oxygen before and after reaction was studied by XPS.The results indicated a high binding energy Ols peak at 531. 4 eV related to the active oxygen species in the oxidativite coupling of methane. |
