Heat Treatment Conditions for Growth of One-Dimensional Tin Oxide Nanostructures

One-dimensional (1D) tin oxide nanostructures have attracted attention due to their potential applications in gas sensors, transport conducting electrodes, flat display devices, dye based solar cells and catalyst support. In this work, one-dimensional tin oxide nanostructures were synthesized by carbothermal method under different conditions. The crystal Structure and morphology of the grown 1D nanostructures were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). Results showed that increasing heating rate and Ar gas flow rate through the furnace, resulted in increase of the aspect ratio of the 1D nanostructures. This is an important characteristic in growth and utilization of the 1D nanostructures
