摘要：
A core-hollow shell composite composed of a nickel (Ni) nanoparticle core encapsulated in a hollow silica shell (Ni@SiO2) was prepared by using a nanocrystalline salt of nickel tris-hydrazine complex, which acted as not only a nickel source but also a solid template to produce the core-hollow shell structure. Structural characterizations using TEM and N-2 adsorption-desorption measurements of the thus-obtained Ni@SiO2 powder revealed that it was composed of a Ni nanoparticle core of ca. 4.0 nm in diameter and a rectangular-shaped hollow silica shell with a micropore (ca. 0.5 nm in diameter) system.
