Large-scale synthesis of rutile SnO2 nanorods

A high yield of tin oxide (SnO2) nanorods was obtained via annealing a nanoscale precursor in the molten salt flux and surfactant. X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, selected area electron diffraction and infrared spectroscopy showed that the nanorods are composed of SnO2 with rutile structure. The surfactant and temperature have a profound influence on the production of SnO2 nanorods.
