| 中文摘要: |
| 非晶态合金是一类介于晶态和无定形物质之间的特殊材料,其组成元素之间以金属键相连并在几个晶格常数范围内保持短程有序而长程无序,这种独特结构使其具有优良的催化性能,并大多被用于加氢反应例如,苯加氢制环己烷[1,2],硝基苯加氢制苯胺[3,4],环戊二烯选择加氢[5],腈类加氢[6, |
| 英文摘要: |
| The ultrafine Ni-B,Ni-La-B,Ni-Ce-B and Ni-Fe-B amorphous alloys were prepared by chemical reduction.The catalytic performance of the amorphous alloy catalysts was measured during liquid phase hydrogenation of furfural.The relationship between the catalyst performance and the structure of catalyst,surface electronic state of the amorphous alloy was systematically studied based on a series of characterization of catalysts(XRD TEM XPS).The results show that the promoting effect of the La,Ce and Fe dopant is significant but the reason is somewhat different. |
