In this research work Cadmium oxide (CdO) nanorods were synthesised by chemical bath deposition on a CdO film deposited via DC sputtering deposition on a silicon substrate. The produced nanorods were characterized by scanning electron microscope (SEM), Atomic force microscope (AFM), X-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS) etc. CdO-Carbon nanostructures hybrids were grown by acetylene chemical vapour deposition on the nanorods at different temperatures with the CdO rods as the catalyst for the carbon nanostructures growth. For comparison a thin film of Fe was deposited to act as the catalyst for the carbon nanostructures growth. The different structures grown using the two different catalysts were exposed to LPG and Nitrogen gases while monitoring the change in the sensors electrical resistances. The electrical responses of the sensors to LPG gas were investigated at different operating temperatures and different gas concentrations.
