An analysis of the transmission electron microscopy image revealed that these nanoribbons have a well-defined shape, with a typical width in the range of 70-300 nm. In general, the nanostructured ribbons were more than 100 mum in length. The results reported here support the hypothesis that this ribbon-like nanostructured material grows by a vapor-solid process. This study introduces two hypotheses to explain the SnO2 nanoribbon growth process.125-128engSnO2 nanoribbonscarbothermal reduction process.Synthesis of SnO2 nanoribbons by a carbothermal reduction processArtigo10.1166/jnn.2002.094WOS:000176029100002Acesso restrito
