摘要：
Carbon nanotubes (CNTs)-supported amorphous Ni-B catalysts were prepared by selectively depositing Ni-B particles inside or outside the CNTs (Ni-B-in/CNTs or Ni-B-out/CNTs). Hydrogenation of chloronitrobenzenes was carried out to test how the Ni-B particle-loading method over the CNTs affected the catalytic performance. Compared with the Ni-B-out/CNTs, the Ni-B-in/CNTs, because of the nanospace limitation inside the CNTs, restricted the size and aggregative behavior of the Ni-B particles better, and formed an amorphous Ni-B alloy with high thermal stability. The Ni-B-in/CNTs exhibited a much higher catalytic activity for hydrogenation of chloronitrobenzenes than the Ni-B-out/CNTs. (C) 2016 Elsevier B.V. All rights reserved.
