In this work, we report the synthesis of tin oxide (SnO<jats:sub>2<\/jats:sub>) nanowires on gold-catalyzed silicon substrate by carbothermal reduction process. SnO<jats:sub>2<\/jats:sub> nanowires were synthesized with SnO<jats:sub>2<\/jats:sub> and graphite powders as the source materials at atmospheric pressure and temperature of 900\u00b0C in the ambience of nitrogen (N<jats:sub>2<\/jats:sub>) gas. First, the effect of source material ratio SnO<jats:sub>2<\/jats:sub>:C on growth of SnO<jats:sub>2<\/jats:sub> nanowires was studied. The structural, morphological and compositional properties of the samples were investigated by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy. The scanning electron microscopy investigation reveals that uniform dense nanowires of SnO<jats:sub>2<\/jats:sub> (diameter ~127\u2009nm and length ~40\u2009\u00b5m) were synthesized with vapour\u2013liquid\u2013solid mechanism. Ultraviolet\u2013visible spectra estimate that the optical band gap of the synthesized SnO<jats:sub>2<\/jats:sub> nanowires was 3.72\u2009eV. Second, the gas sensing performance of synthesized SnO<jats:sub>2<\/jats:sub> nanowires was investigated by testing with carbon monoxide (CO), Methane (CH<jats:sub>4<\/jats:sub>) and methanol (CH<jats:sub>3<\/jats:sub>OH) gases at different operating temperatures and concentrations. Results indicate that the synthesized SnO<jats:sub>2<\/jats:sub> nanowires are highly promising for gas sensing applications.
