A novel and low-temperature hydrothermal synthesis of SnO ₂ nanorods

SnO ₂ nanorods with the rutile structure have been successfully synthesized by a novel hydrothermal method. This process requires no high temperature. In this reaction, the surfactant cetyltrimethyl ammonium bromide (CTAB) plays an important template-directed role. Select-area electron diffraction (SAED) and X-ray diffraction (XRD) showed that the nanorods were crystalline with the rutile structure. The morphologies of the as-prepared products were characterized by scanning electron microscopy (SEM). The effect of the concentration of SnCl ₄ on the morphology was discussed.
