Abstract

Abstract : Pure and Ni doped ZnO nanorods were successfully synthesised via a simple hydrothermal synthesis method and characterised by X-ray powder diffraction, field emission scanning electron microscopy, transmission electron microscopy (TEM) and high resolution TEM respectively. Sensing properties were systematically measured towards acetylene gas (C2 H2 ). The Ni doped ZnO gas sensor exhibits excellent gas sensing performances, such as lower working temperature, higher gas response, rapid response and recovery time, than those of pure ZnO gas sensors. All results demonstrate the potential of Ni dopant for improving the gas sensing properties of ZnO gas sensors to C2 H2 gas.
