以碳纳米管为还原剂，在600℃下通过还原法制备了镍纳米颗粒，并将其均匀负载在多壁碳纳米管（MWCNTs）上。制备的镍纳米颗粒为面中心立方相单晶，尺寸分布在10 ~ 50 nm之间，通过透射电镜（TEM）、高分辨率透射电镜（TEM）和x射线衍射（XRD）对其进行了表征。这些镍纳米粒子将被涂上石墨烯层。在600℃乙炔中，镍纳米粒子的矫顽力值优于常温下的牛镍。(c) 2005爱思唯尔公司版权所有。
Nickel nanoparticles were prepared and uniformly supported on multi-walled carbon nanotubes (MWCNTs) by reduction route with CNTs as a reducing agent at 600 degrees C. As-prepared nickel nanoparticles were single crystalline with a face-center-cubic phase and a size distribution ranging from 10 to 50 nm, and they were characterized by transmission electron microscopy (TEM), high-resolution TEM and X-ray diffraction (XRD). These nickel nanoparticles would be coated with graphene layers. when they were exposed to acetylene at 600 degrees C. The coercivity values of nickel nanoparticles were superior to that of bull, nickel at room temperature. (c) 2005 Elsevier Inc. All rights reserved.
