This work aimed to analyze the role of nanostructure in gas sensing. For this purpose, as functional material, a TixSn1-xO2 system has been chosen because of the wide difference in grain dimension obtained by varying the stoichiometry (0.1<x<0.9) of the synthesised powders. The role of nanostructured grains has been investigated both for large specific surface offered and for the influence in reducing the surface charge density; a special model in this respect has been reviewed, discussing about the characteristic length below which a material can be properly considered as nanostructured
