| 摘 要： | The partial oxidation of ethanol to hydrogen was investigated over Ni/Fe/La catalysts prepared by the co-precipitantion method.the effects of introduction of La promoter and the reaction temperature on the catalytic performance were studied.It was found that the introduction of La into Ni/Fe catalysts is helpful to increase the selectivity to hydrogen and the stability of the catalysts.The results of XRD and XPS characteri-zation show that the structure of the catalyst was changed during the reaction.The existence of LaFeO3 species is possibly the main reason of the increase of the catalyst stability.

| Abstract: | The partial oxidation of ethanol to hydrogen was investigated over Ni/Fe/La catalysts prepared by the co precipitation method. The effects of introduction of La promoter and the reaction temperature on the catalytic performance were studied. It was found that the introduction of La into Ni/Fe catalysts is helpful to increase the selectivity to hydrogen and the stability of the catalysts. The results of XRD and XPS characterization show that the structure of the catalyst was changed during the reaction. The existence of LaFeO 3 species is possibly the main reason of the increase of the catalyst stability. |
