Gas Sensing to CH_3CH_2OH of Y-doped ZnO Nano-Spheres Prepared by Electros Spinning

通过调节前驱液组分,使用电纺丝法和煅烧工艺,制备出了Y掺杂ZnO球形结构纳米颗粒。研究表明,与纯ZnO相比,Y掺杂ZnO纳米颗粒具有分布粒度更窄,结构更疏松。传感性能研究发现,在相同的CH_3CH_2OH浓度下,基于Y掺杂ZnO球形结构纳米颗粒的传感性优于纯ZnO颗粒,具有更宽的传感浓度区间和更稳定的传感性能,是一种潜在的CH_3CH_2OH传感器制造材料。

Y-doped ZnO nano-spheres were fabricated by electricity spinning method and subsequent calcination process. It is found that Y-doped ZnO nano-spheres have a smaller the particle size, and the more loose structure. Investigation on the sensor performance shows that, at the same CH3CH2OH concentration, the sensing performance of Y-doped ZnO nanosphere is superior to that of pure ZnO particles, and shows the stable sensing properties. The Y-doped ZnO nanosphere could be used as a promising sensor manufacturing material for CH3CH2OH.
