Zinc and Tin composite nanostructures were fabricated as gas sensors on the interdigitated ITO (Indium Tin Oxide) electrodes. Zinc oxide (ZnO) and Tin dioxide (SnO₂) nanostructures were grown at 900℃ in the Vapor-Liquid-Solid(VLS) growth mechanism in a furnace. FE-SEM images in Figure 1 illustrated the composite nanostructures of ZnO-SnO₂, called “Nano-vine”. The normal metal catalysts such as Au and Cu were replaced with the Tin in the ITO electrodes. The Nano-vine was partially more sensitive in the detection sensitivity of noxious gases such as NO₂, CO and NH3 than that produced by nanostructures using Zn or Sn
single material powders.
