Bamboo-like Te nanotubes were synthesized via the galvanic displacement reaction of NiFe nanowires with Ni-rich and Fe-rich segments. The thick and thin components of the synthesized Te nanotubes were converted from the Ni-rich and Fe-rich segments in the NiFe nanowires respectively. The dimensions of the Te nanotubes were controlled by employing sacrificial NiFe nanowires with tailored dimensions as the template for the galvanic displacement reaction. The segment lengths of the Te nanotubes were found to be dependent on those of the sacrificial NiFe nanowires. The galvanic displacement reaction was characterized by analyzing the open circuit potential and the corrosion resistance.
