In the present work, we have synthesized single crystalline In2O3octahedra via a vapour phase transport at high temperatures over Si/SiO2substrates. Gas sensing measurements (NO2) have been performed under temperature variations and UV irradiation. Optimum working conditions for each case have been found. A comparison between nanostructured In2O3and commercial In2O3powder has been performed in order to show the advantages of using a nanostructured based sensor. As a result, the detection of low concentrations of NO2(50 ppb) has found to be possible with sensitivities for higher concentrations comparable to those shown in recent publications.
