Structure and Acetylene Sensing Behavior of Zinc Oxide Nanowires Based Gas Sensor

Abstract:

Low-dimensional semiconducting metal oxide nanostructures have gained great interest for developing high performance chemical gas sensors. In this study, we successfully synthesized quasi one-dimensional zinc oxide nanowires via a simple and facile hydrothermal process with zinc acetate dihydrate as precursor and polyethylene glycol as surfactant. The crystalline structures and microstructures of the as prepared samples were investigated by X-ray powder diffraction and field emission scanning electron microscopy, and a possible growth process was discussed in detail. Moreover, thick film gas sensor was fabricated with the as prepared nanowires and its sensing properties to acetylene gas, an important fault characteristic gases dissolved in oil-filled power equipments was measured.
