Abstract

This Paper investigates the use of TiO2 nanowires and nanotetrapods on glass and silicon substrates for sensing combustible gases such as LPG (Liquid Petroleum Gas) and Oxygen. The growth of Titanium dioxide (TiO2) nanowires/nanorods/nanotetrapods was investigated using both physical and chemical methods. In thermal evaporation method, both with and without vacuum conditions, was employed to synthesize various TiO2 nanostructures. A vacuum coating machine was utilized to create uniform TiO2 thin films, which were subsequently employed in both thermal evaporation methods and chemical methods for the growth of TiO2 nanowires. For the thermal evaporation method without vacuum, Thermal Gravimetric Analyzer equipment was used to facilitate the growth of TiO2 nanowires on TiO2-coated silicon thin films. The impact of using microwave radiation for heating and use of capping agent during the chemical synthesis of TiO2 nanowires was studied in detail. The produced samples were characterized at various stages for UV absorption spectroscopy, particle sizing, structural and morphological analysis. Under structural analysis, XRD of TiO2 nanowires/nanotetrapods samples on glass were obtained and the size of TiO2 nanostructure was calculated using Scherrer’s formula. Based on these properties, TiO2 nanowires /nanotetrapods samples were extensively studied for different gas sensing applications. The gas sensing experiments were conducted using the TiO2 nanowires and the TiO2 nanowires/nanotetrapods samples for varying gas volume concentrations.

Keywords: Titanium dioxide (TiO2) nanowires, Liquid Petroleum Gas (LPG), Recovery response, Sensitivity, Gas sensor applications.
