Abstract

Metal oxide-based nanocomposites has been regarded as a useful tool for sensors technology to detect various hazardous gases at low concentrations. In this work, the CeO2–ZnO composite was successfully synthesized using a simple chemical combustion method. The synthesized samples were characterized by employing different characterization techniques. The results demonstrated that the cubic fluorite phase of CeO2 and the hexagonal wurtzite phase of ZnO have been obtained while the CeO2–ZnO composite showed a mixed phase of CeO2 and ZnO. The morphology of the CeO2–ZnO products has a nanoporous structure. The well-defined structure of the CeO2–ZnO nanocomposite was confirmed by the HR-TEM. Furthermore, gas sensing study showed that CeO2–ZnO nanocomposite exhibited enhanced sensing properties toward ethanol at an operating temperature of 275 ℃. The gas sensitivity value was 61.75% toward 24 ppm ethanol. This could be attributed to the formation of the n–n heterojunction between CeO2 and ZnO which enhances conductivity value to give more sensitivity.

化学燃烧合成 CeO2-ZnO 纳米复合材料及其在乙醇传感中的应用
基于金属氧化物的纳米复合材料已被视为一种有用的传感器技术工具,可用于检测低浓度的各种有害气体。本研究采用简单的化学燃烧法成功合成了 CeO2-ZnO 复合材料。采用不同的表征技术对合成样品进行了表征。结果表明,获得了 CeO2 的立方萤石相和 ZnO 的六方钨锌相,而 CeO2-ZnO 复合材料则显示出 CeO2 和 ZnO 的混合相。CeO2-ZnO 产品的形态具有纳米多孔结构。HR-TEM 证实了 CeO2-ZnO 纳米复合材料的明确结构。此外,气体传感研究表明,在 275 ℃ 的工作温度下,CeO2-ZnO 纳米复合材料对乙醇的传感性能增强。对 24 ppm 乙醇的气体灵敏度值为 61.75%。这可能是由于 CeO2 和 ZnO 之间形成了 n-n 异质结,从而提高了传导值,使灵敏度更高。

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.
