| 中文摘要: |
| 采用共沉淀法制备的Cu/Fe催化剂催化甲醇部分氧化制氢结果表明，Fe的引入，有利于降低CO选择性，Cu/Fe比对催化性能有明显影响，当Cu/Fe比为2：8时，甲醇转化率最高，与其它的Cu基催化剂相比，在较宽的Cu/Fe比范围内，CO的选择性均保持在较低的水平，利用XRD，XPS等方法，对Cu/Fe催化剂进行表征，结果表明，Fe的引入，有利于活性组分Cu在催化剂表面上的分散，在反应过程中Cu组分向表面富集，因而可使得催化剂表面的Cu物种不因Fe的引入而减少。 |
| 英文摘要: |
| Hydrogen production by methanol partial oxidation over Cu/Fe catalysts prepared by co\|precipitation method has been studied in detail in this paper. It is found that the introduction of Fe is favorable of decrease of CO selectivities of Cu/Fe catalysts. And the variation of Cu/Fe ratios resulted in the remarkable variation of activities of catalysts. When Cu/Fe ratio is 2:8, methanol conversion is highest. Compared with other Cu based catalysts, Cu/Fe catalysts exhibits lower CO selectivities under the wide variation of Cu/Fe ratios. The results of XPS, XRD, and Mssbauer characterizations showed that the enrichment of Cu species on the surface of Cu/Fe catalysts occurred during methanol partial oxidation reaction. And the higher amount of Fe introduction makes Cu species highly dispersed. |
