Carbon Nanotubes Functionalized by Nanoparticles of Platinum

Abstract:

Carbon nanotubes (CNT) based gas sensors have attracted interest due to their excellent properties. Several studies have reported changes in the CNT’s electrical properties when functionalized with platinum (Pt) nanoparticles. In this investigation, the vapor phase impregnation decomposition (VPID) method was employed to incorporate Pt nanoparticles on CNT. Both, Pt nanoparticles and CNT were characterized by high resolution transmission electron microscopy (HR-TEM). The sensitivity of sensors based on CNT doped with Pt, was evaluated with ozone molecules. TEM images showed low and heterogeneous distribution on the surface of carbon nanotubes. The gas evaluation of CNT-Pt sensor presents good and quick response to ozone molecules at different concentrations and temperatures. The best response was found to be at 120 °C.
