Gas sensing properties of CVD grown tungsten oxide nanowire films

Single crystalline, tungsten oxide nanowires (NWs) loaded with metal oxide nanoparticles (NPs) are very promising for developing a new generation of inexpensive, yet highly sensitive and more stable gas sensors. By supporting p-type metal oxide NPs (e.g. Pd, Cu, Ni, Co or Ir oxides) on n-type metal oxide NWs, both chemical and electronic sensitization effects can be obtained, which can dramatically tune the response to target gases of the resulting hybrid nanomaterials, thus enabling the engineering of selectivity. I will discuss the aerosol-assisted chemical vapour deposition (AACVD) technique, which enables growing single crystalline, n- type metal oxide NWs supporting homogeneously distributed, mono-modal, p-type metal
