Formation of Spinel Nanotubes
|
The fabrication of hollow nanotubes is important for potential application as high-efficiency catalysts or drug-delivery agents. Such nanotubes can be prepared by different way such as rolling up layered materials or via an axial growth in a rolled-up form, coating pores in templates or by eliminating the core of a core–shell nanowire. A spinel-forming interfacial solid-state reaction of core–shell nanowires involving the Kirkendall effect of counter diffusion was demonstrated as a new innovative method for nanotube formation.
