Influences of the mole ratio SnO2/NaOH on the growth of SnO2 nanorods

Abstract

SnO₂ nanorods have been successfully prepared by hydrothermal method at low temperature. The mole ratio of SnO₂/ NaOH plays important role in the morphology and diameter of SnO₂ nanorod. Besides, the possible growth mechanisms of SnO₂ nanorods are also discussed. Structural properties and surface morphologies of the SnO₂ nanorods were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The experimental results show that diameters of the nanorods are around 100 nm to 300 nm with lengths of several micrometers. With the success of preparing SnO₂ nanorods, which will improve in the research and preparation of gas sensor based on SnO₂ materials.

Keywords: SnO₂, nanorods, hydrothermal method.
