Abstract

Single crystalline copper oxide nanoribbons were synthesized via a surfactant-assisted hydrothermalroute. The resulting CuO nanoribbons contain substantial amounts of nanorings and nanoloops. Highresolution TEM analysis identified CuO nanoribbons growing along the [010] direction. CuOnanoribbons exhibited excellent sensing performance towards formaldehyde and ethanol vapours withrapid response and high sensitivity at low operating temperatures. We found that the loading of a smallamount of Au or Pt nanoparticles on the surface of CuO nanoribbons can effectively enhance andfunctionalize the gas sensing performance of CuO nanoribbons.
