AuPd alloy nanoparticles functionalized ZnO: enhanced ethanol sensing performance

In this paper, AuPd alloy nanoparticles (NPs) are prepared by co-reduction method using double reducing agents. Different mass percentages of AuPd alloy NPs loaded ZnO nanomaterials are prepared by classical impregnation method. The gas sensing properties of the sensor are studied. 0.5 wt% AuPd–ZnO exhibits a higher gas sensing response (Ra/Rg = 32, 50 ppm ethanol), which is 1.88 times that of ZnO gas sensing response. At the same time, the response/recovery time is 2 s/29 s. Compared with ZnO, the recovery time is reduced by 55 s. At last, the sensing mechanism in the process of gas sensing test is analyzed based on AuPd alloy NPs and ZnO.

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
