Preparation of Ni Nano-particle by Rotary Chemical Vapor Deposition

Abstract

Carbon layer and carbon nanotube encapsuled Ni nanoparticles were prepared on α-Al₂O₃ support powder by rotary CVD using nickelocene as a precursor. The effect of deposition temperature (T_dep) on microstructure and compositions was investigated. The Ni content increased with increasing T_dep at 413–813 K. The highest Ni content was 2.1 mass% at 813 K. The carbon layer encapsuled Ni nanoparticlues was obtained at 613 K. Carbon nanotube encapsuled Ni nanoparticles was obtained at 893 K.
