Abstract
A novel structure of SnO2 nanorods arrays had been firstly synthesized by a facile one-step hydrothermal route in the absence of substrates and without any surfactants. X-ray diffraction spectra (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) were used to examine the morphology and phase structure of SnO2 nanorods arrays. The results show that the nanorods array is built by two layers of rutile structure SnO2 nanorods with the diameter of 25nm and the height of 200–300nm. The two layers of SnO2 nanorods are in the opposite growth direction. A plausible formation mechanism of SnO2 nanorods arrays was proposed in this paper.
