Recent developments in the direction of semiconducting oxide nanostructures have provided new dimensions in energy harvesting and storage, battery materials, solar cells, flat panel displays and others in terms of miniaturization, response and cost effectiveness [1]. Beside zinc oxide, tin oxide is the second most important member in the class of metal oxide semiconductors. It is currently undergoing different processes of synthesis to produce cost effective electronics and other devices. Several complicated synthesis methods, starting from vapor liquid solid, have been used to synthesize 1-D nanostructures of tin oxide. In present work we report a very simple flame assisted versatile and cost effective technique for growing SnO2 nanorods, nanowires, nanobelts and their networks with macroscopic expansion on the cm scale. Growth and crystalline nature of nanorods were investigated by high resolution transmission electron microscopy, which revealed [100] and [101] growth and twin boundary propagation. Mechanical properties of tin oxide nanobelts and electrical properties of nanorods will be discussed.
