Growth of Sb2O3 Nanotubes via a Simple Surfactant-assisted Solvothermal Process

Sb2O3 nanotubes were successfully prepared via a simple surfactant-assisted solvothermal method. The nanotubes have an orthorhombic structure with outer diameter range from 40 to 150 nm, the wall thickness of 10 to 40 nm and a length of up to several micrometers. The formation of nanotubes followed a rolling-up mechanism.
