首次用化学还原法制备了非晶态Ni-W-P合金微粒.应用X射线衍射(XRD)、差热分析(DSC)、透射电子显微镜(TEM)和X射线光电子能谱(XPS)等方法对该微粒进行了表征.考察了该微粒催化环戊二烯加氢的活性,并与Ni-P非晶态合金对比,发现少量的W的加入改变了Ni-P的加氢活性.
The amorphous Ni-WP alloy particles were prepared by the chemical reduction method for the first time.It was characterized by X-ray diffraction (XRD), differential thermal analysis (DSC), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) The catalytic activity of the particles in the hydrogenation of cyclopentadiene was investigated and compared with that of Ni-P amorphous alloys. It was found that the addition of a small amount of W changed the hydrogenation activity of Ni-P.
