Quasi ID crystals of tin and indium oxide have been prepared by vapor phase technique. Structural characterization has been performed by transmission electron microscopy in correlation with the study of the electrical gas sensing properties in presence of different concentrations of carbon monoxide and acetone as function of the working temperatures. Tin dioxide nanowires showed superior gas sensing...
In the present work, we have analyzed the feasibility of several metal/semiconductor systems for metal additive superficial clustering. To this aim, we have selected the most common semiconductors (SnO 2 and TiO 2 ) and catalytic metal species (Pt, Pd and Nb) used for gas sensing. The application of nanoscopical techniques such as high resolution electron microscopy and the complementary...
