Novel bismuth nanotube arrays synthesized by solvothermal method

Novel bismuth nanotube arrays have been successfully synthesized by a solvothermal method through the reduction of bismuth oxide (Bi2O3) by ethylene glycol (EG). The productions were characterized by XRD, TEM and HRTEM. The diameter of the nanotubes is about 3–6 nm and length is up to 500 nm. The possible growth mechanism of Bi nanotubes was discussed.
