Nanoscale Ni-B amorphous alloy catalyst supported on carbon nanotubes

摘要：

Heat treatment of carbon nanotubes (CNTs) was carried out under ammonia atmosphere and then CNTs were modified by Triton x-100 (CNTs-T).Ni-B amorphous alloy catalysts supported on CNTs and CNTs-T were prepared by impregnation-chemical reduction method.The catalysts were characterized by TEM,ICP,XRD,BET and CO chemisorption,and studied in the acetylene selective hydrogenation.The results show that homogeneous Ni-B amorphous particles with mean size about 10 nm are successfully prepared on CNTs-T.Compared with Ni-B/CNTs,nickel loading of Ni-B/CNTs-T is increased by about 14.6％.Furthermore,the activity and selectivity of Ni-B/CNTs-T are much higher than those of Ni-B/CNTs in the acetylene selective hydrogenation under comparative condition.
