Design and Growth of Metal Oxide Film as Liquefied Petroleum Gas Sensors
Nowadays innovations in synthesis methods for metal oxide-based nanomaterials such as nanostructured and both physical and chemical route techniques have been adopted by various researchers around the world. The investigation has been focusing on various deposition parameters for fabricating nanostructured metal oxide. Gas sensors that use metal oxide materials are broadly utilized in industry to monitor combustion processes. While they are economical to powerful in high temperature environments, many of these instruments are not selective towards the species of interest when placed in a stream composed of multiple gases. Research on nanostructured metal oxide materials has generated great interest in scientific community. Metal oxide is a chemically stable, harmless, biocompatible, inexpensive material with very high dielectric constant and interesting photocatalytic activities. It is a wide-gap semiconductor and depending on its chemical composition, it shows a large range of electrical conductivity. Synthesis strategies regarding nanocomposites of metal oxide with other inorganic and organic materials sensing activities has been reviewed. The measure response of metal oxide film-based sensor highat low concentration of LPG.
