Abstract
  • Tin oxide (SnO(2)) and zinc oxide (ZnO) nanostructures are widely studied because of their peculiar physical and chemical properties and the large number of possible application fields. Surface functionalization of these materials is a very important topic because it is a powerful tool for modifying or tuning their properties, in order to better match the device requests. For example, palladium/palladium oxide (Pd/PdO) nanoparticles are often used to enhance selectivity of chemoresistive gas sensing properties of metal-oxide nanostructures. SnO(2) nanowires and ZnO nanotetrapods have been grown on large areas by a combination of metal evaporation and controlled oxidation, while a MOCVD (Metal Organic Chemical Vapor Deposition) process has been chosen in order to deposit Pd/PdO nanoparticles on the surface of the obtained oxide nanostructures. Samples morphology, structure and composition have been studied by means of SEM and TEM microscopy, EDS microanalysis and X-Ray diffraction. The different results, obtained as a function of the synthesis and annealing parameters, are discussed focusing the attention to the experimental conditions that allowed the authors to obtain an optimal \"spotted\" coverage of oxide nanostructures, which is often required for gas sensing application.
