Description
The benzene hydrogenation activities of ultrafine Ni-B amorphous alloys show that a maximum appears at the annealed temperature of 350 degree C, which is about one time higher than that of initial sample. The XRD results indicate that the nanocrystalline Ni3B and small amount of Ni2B are produced in the annealed temperature region between 300 and 350 degree C. Large amount of Ni-B alloy is further crystallized into metal Ni at 400 degree C or higher temperature. The authors have found that the nanocrystalline Ni3B possesses a highly catalytic activity for benzene hydrogenation by compared with ultrafine Ni-B amorphous alloy
