Tin oxide nanobelts in different states of oxidation were produced by carbothermal reduction at 1260 ºC. The nanostructures were characterized by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy. The state of oxidation of the nanostructures was controlled by the synthesis atmosphere inside the furnace. The materials obtained in atmospheres without oxygen were SnO and SnO2 nanobelts, while atmospheres with oxygen (about 10%) only allowed for the growth of SnO2 nanobelts.
