Abstract

In this study, for the synthesis of one-dimensional zinc oxide (1D ZnO) nanorods (NRs) on glass substrate, a simple hydrothermal method has been used. The morphological, microstructural and gas sensing properties of as-prepared 1D ZnO has been studied and reported. XRD investigation demonstrates the formation of the hexagonal wurtzite crystal structure of 1D ZnO. Field emission scanning electron microscope conspicuously evinces the as-prepared sensor film composed of one-dimensional nanorods. As-prepared one dimensional ZnO nanorods are utilized for sensing of baneful nitrogen dioxide gas. The one dimensional ZnO nanorods sensor shows the furthest response of 900% for NO2 gas at an optimized operating temperature of 200 °C along with the rapid response and recovery time. In adding up, one dimensional ZnO sensors also respond to an extremely least coverage for NO2 gas.
