Flower-like SnO2 architectures constructed of one-dimensional tetragonal prism nanorods were synthesized by a simple hydrothermal method using ethanol as dispersant agent. The morphology and structure of crystals were characterized by field emission scanning electron microscopy (FE-SEM), Xray diffraction (XRD) and high resolution transmission electron microscopy (HRTEM). The results revealed that the SnO2 nanorods exhibited a single crystalline rutile structure with aspect ratio of nearly 20, and lattice fringes of (1 0 1) plane was 0.263...
