Abstract

ZnO sensors were fabricated from ZnO nanorods prepared by ultrasound radiation method and their gas sensing properties were investigated for NO, (CH3)3N, H2S, CO and CH3SH. In a procedure, zinc nitrate hydrate [Zn(NO3)2·6H 2O] and hexamethyleneteramine [C6H12N 4,] were dissolved in deionized water and then the solution was irradiated with high intensity ultrasound radiation for 1h by employing a direct immersion titanium horn. The lengths of ZnO nanorod were from 250 nm to 500 nm and the diameters were from 40 nm to 80 nm. The size of ZnO nanorod can be controlled by concentration of solution. The sensing characteristics of these nanostructures were investigated for three kinds of sensor fabricated by different concentrations (0.01, 0.005 and 0.001 M) of solution. We observed that the property of sensors was influenced by the morphology. Crystal structure and ceramic microstructure of ZnO nanorod were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
