The physico-chemical properties and the difference in catalytic activity of Pd catalysts prepared by bio- logical reduction method and chemical method, respectively, were investigated using XRD, TEM and specific surface char- acterization methods. The catalytic properties of catalysts were studied through activity evaluation means. The test results showed that the catalysts prepared by biological method were characteristic of small Pd nanoparticle size, good dispersion and low agglomeration, while possessing a high activity and stability in styrene hydrogenation reaction in comparison with catalysts prelgared via the chemical method.展开更多
文摘This paper relates to highly dispersed supported Pd/MWCNTs and Fd/a-Al2O3 catalysts prepared by biological reduction method. The physico-chemical properties and the difference in catalytic activity of Pd catalysts prepared by bio- logical reduction method and chemical method, respectively, were investigated using XRD, TEM and specific surface char- acterization methods. The catalytic properties of catalysts were studied through activity evaluation means. The test results showed that the catalysts prepared by biological method were characteristic of small Pd nanoparticle size, good dispersion and low agglomeration, while possessing a high activity and stability in styrene hydrogenation reaction in comparison with catalysts prelgared via the chemical method.
