摘要
Pd doped nano-ZnO were prepared by solution combustion synthesis (SCS), using tartaric acid as fuel and zinc nitrate as oxidant. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and fluorescence spectroscopy, and the influence of Pd-doping on the gas sensing properties of ZnO was mainly discussed. The results indicate that at 330℃, the gas sensitivity of 0 and 7 at% Pd-doped sensors to 5.0×10-5 ethanol gas were 21.4 and 11.2, to 5.0×10-5 acetone gas were 2.0 and 8.8, respectively. The selectivity of sensors to ethanol and acetone was significantly improved via Pd-doping. ©, 2015, Journal of Functional Materials. All right reserved.
