基于Fe@ZnO纳米材料的高灵敏度乙醇传感器

A Highly Sensitive Ethanol Sensor Based on Fe@ZnO Nanoparticles at Room Temperature

采用化学还原法和溶胶凝胶法制备具有核壳结构的Fe@ZnO纳米材料,通过X-射线衍射(XRD)、扫描电子显微镜(SEM)等测试手段对Fe@ZnO纳米颗粒的形态、结构等进行表征,用此核壳结构的乙醇传感器在室温下检测乙醇,研究该纳米材料对乙醇的传感特性。Fe@ZnO是一种很有前途的、可用于检测室温下低浓度的乙醇气体的传感器,该传感器性能稳定、反应灵敏。对Fe@ZnO纳米颗粒的乙醇传感特性的系统研究有助于开发检测乙醇气体的传感器。

Fe@ZnO nanomaterials with nuclear core shell structure were prepared by chemical reduction and sol gel methodion.X-ray diffraction(XRD)and scanning electron microscopy(SEM)nanoparticles were used to describe the morphology and structure of Fe@ZnO,ethanol sensors with this nuclear-shell structure were used to detect ethanol at room temperature and to study the sensing properties of the nanomaterials on ethanol.Fe@ZnO was a promising,stable and responsive sensor for detecting low concentrations of ethanol gas at room temperature.Systematic studies of the ethanol-sensing properties of Fe@ZnO nanoparticles could facilitate the development of sensors to detect ethanol gases.
