Abstract: In this work, we reported a high-performance ethanol gas sensor based on novel Pd@ZnO core@shell nanoparticles (CSNPs). The Pd@ZnO CSNPs were synthesized by chemical method and characterized by XRD, TEM and EDS techniques. Gas sensing results demonstrated that Pd@ZnO CSNPs show high sensitivity and remarkable selectivity towards ethanol at 250 C. The response value of Pd@ZnO CSNPs is 152, which is almost six times higher than the response value (27) of ZnO NPs at 250 C. The mechanism of enhancement in sensing properties can be ascribed to the chemical and electronic sensitization effect of Pd NPs and also due to the unique core@shell structure. These characteristics may shed light on the development of a selective ethanol sensor based on Pd@ZnO CSNPs.
