Abstract

SnO₂ nanomaterials were synthesized using the unseeded, non-catalytic horizontal vapor phase growth (HVPG) deposition. The sample was synthesized at a growth temperature of 1200°C and growth time of 6 hours. The resulting nanostructures ranges from nanowires, nanorods to nanobelts as confirmed by JEOL JSM 5310-SEM. Backscattered electron image observations showed that nanobelts has minimal vividness that suggest a distinct composition compared to nanorod and nanowire images. Using Energy Dispersive X-ray (EDX) analysis, it was confirmed that the nanobelts are oxygen deficient that comprises SnO while the nanorods and nanowires are made of the more common SnO₂. From these findings, a growth mechanism was proposed detailing the transition of the SnO₂ nanostructures from the powder SnO₂ source material.
