摘　　要：非晶态超微粒子，镍基合金，硼合金，合金催化剂。ltra-fine amorphous alloy catalysts were prepared by chemical reduction of Ni2+ with NaBH4, and the effect of different preparation conditions on the composiion, specific surface area and dispersity of Ni-B alloyswas studied. The catalysts were characterized by methods of elementaryanalysis, XRD, TEM, electronic diffraction etc. The results of benzenehydrogenation showed that the catalytic activity of Ni-B alloys is relativeto their specific surface area. The greater the specific surface area is, thehigher the catalytic activity.
