| 英文摘要 | autothermal reforming of methane was studied over la-doped ceria-zirconia-supported rh catalysts. the ch4 conversion increased from 49 to 60% on increasing the content of la3+ from 5 to 15%, while further increase in the la3+ content led to a slight decrease on both ch4 conversion and h-2 selectivity. h-2-tpr and uv-vis drs spectrum showed that the interaction between rh and the support was enhanced by increasing the content of la. we speculated that a so-called "rh-la interfacial species" was formed on the surface of the support, which played an important role in catalytic activity. the balance between exposed rh and the "rh-la interfacial species" was necessary to improve the catalytic activity. upon increasing the rh loading on 15% la-doped ceria-zirconia support, the balance was built, i.e., ch4 conversion increased from similar to 60 to 69% by increasing rh loading from 0.1 to 0.5 wt% and only 2% conversion was elevated by doubling the rh loading from 0.5 to 1.0 wt%. |
