One-dimensional (1-D) nanostructures of metals and metal-oxides are currently the subject of intense research in order to discover fundamental science at the nanoscale as well as for their potential as sensing, catalytic, and electronic applications. Furthermore, the development of nanotechnology has significantly generated cost savings in materials. Here, I will show you some sensor performances obtained by using 1-D nanostructures; metal-oxide nanowires based electronic noses, as well as the synthesis and properties of 1-D novel metal-oxides such as VO2, RuO2, Fe3O4 etc. The in-situ Grazing-incidence small-angle X-ray scattering measurements were carried out to investigate the growth mechanism. A heterogeneous catalysis by metal nanoparticles onto metal-oxide nanowires as a functionalization strategy was used, very useful, to design the e-nose showing highly-selective gases detection. |
