摘要：

<正>Flower-like ZnO was prepared through a hydrothermal process using zinc sulfate as raw material.The microstructure and morphology of the samples were characterized by X-ray diffraction （XRD） and transmission electron microscopy （TEM）.XRD results showed that the as-obtained sample could be indexed to hexagonal wurtzite ZnO.TEM results revealed that the ZnO sample presented flower-like shape.The gas sensors were prepared with the traditional sintering process and their gas sensitivities were detected.The gas sensitivity results showed that the sensors based on flower-like ZnO were very sensitive to dilute 90# gasoline.The relatively high sensitivity and selectivity of these sensors made from flower-like ZnO demonstrated the potential for developing a new class of selective gasoline sensors.
