Abstract

Zn(NO3)2 was used as the raw material to prepare one-dimension ZnO through a hydrothermal technique with CTAB controlling ZnO morphology. The products were characterized by X-ray diffraction(XRD), transmission electron microscope(TEM) and scanning electron microscope(SEM). Gas sensors were made by using the ZnO nanorads and their gas sensitivities were measured. The result shows that the ZnO nanorods have lower working temperature than granulated ZnO and have very good sensitivity to 10ppm trimethylamine (TMA), methanol, ammonia, acetone and ethanol at the working temperature of 170℃. The gas sensitivity mechanism of the ZnO rods was discussed.
