Abstract: © 2016 The Authors. One-step Aerosol Assisted Chemical Vapour Deposition (AACVD) method was used for the first time to grow WO3nanoneedles (NNs) decorated with NiO metal nanoparticles (NPs) at lower (380°C) deposition temperature. This co-deposition method is demonstrated to be an effective route to incorporate metal NPs into nanostructured materials. A layer of needle-like tungsten oxide film was deposited directly onto transducer alumina substrates from W(CO)6and Ni(acac)2precursors. Moreover, the systematic growth study of WO3NNs + metal NPs allowed the identification of the parameters required for the formation of nanostructured sensing materials having different metal precursor concentration in a range of 2.5 to 15 mg The results show variations in the sensing properties according to the metal precursor concentration. Improved sensing, to some reducing gases, such as EtOH, H2S and NH3are observed at 200°C with lower doped tungsten oxide films, whereas higher doped tungsten oxide has shown no response.
