Abstract

We report here the first successful synthesis of pure Ni nanotubes by employing the electroless Ni deposition in conjunction with removable amorphous SiOx (a- SiOx) nanowire templates technique. After the 3- aminopropyltrimethoxysilane (APTMS) functionalization, activation, and hydrazine-modified electroless Ni plating processes, a uniform a- SiOx /pure Ni core-shell nanowire structure is produced. By etching away the inner a- SiOx nanowire templates, hollow Ni nanotubes are readily obtained. The observed results present the exciting prospect that with appropriate controls, the hydrazine-modified electroless deposition combined with the APTMS-functionalized a- SiOx nanowire templates technique can be successfully implemented in forming a variety of high-purity, hollow, metal nanotubes.
