Abstract
A simple and easy hydrothermal process has been employed to synthesize flower-like ZnO products consisting of numerous orderly oriented and bundled nanorods. The structure and morphology of the novel ZnO structure are characterized in detail. The flower-like ZnO-nanorod-based gas sensors are investigated for their ethanol-sensing properties, and the results reveal that the sensors exhibit a high response of 143.6 to 1000 ppm ethanol and good selectivity at the optimal operating temperature of 250 ℃. The effect of the flower-like morphology on the response of the gas sensors to ethanol is also investigated.-
