摘要
One-dimensional (1D) ZnO was prepared through hydrothermal synthesis by cetyltrimethylammonium bromide (CTAB) controling its morphology.The products were characterized by X-ray diffraction (XRD),transmission electron microscopy (TEM) and scanning electron microscopy (SEM).The sintered gas sensor was prepared using ZnO nanorods and its gas sensitivity was measured in static gas atmosphere.The result showed that the ZnO nanorods had lower working temperature than granulated ZnO and had very good sensitivity to 10μg/g trimethylamine (TMA),methanol,ammonia, acetone and ethanol at the working temperature of 170℃.SEM picture revealed that there were many multi-pores in the surface of the sensors.These multi-pores might help to absorb gases and improve the gas sensitivity.
