Demands for the detection of harmful gas in daily life have arisen for a period and a gas nano-sensor acting as a kind of instrument that can directly detect gas has been of wide concern. The spinel-type nanomaterial is suitable for the research of gas sensors because of its unique structure. However, the existing instability, higher detection limit, and operating temperature of the spinel materials limit the extension of the spinel material sensor. This paper reviews the research progress of spinel materials in gas sensor technology in recent years and lists the common morphological structures and material sensitization methods in combination with previous works.
在日常生活中,对有害气体检测的需求已经出现了一段时间,而作为一种能够直接检测气体的仪器,气体纳米传感器受到了广泛关注。尖晶石型纳米材料因其独特的结构而适用于气体传感器的研究。然而,尖晶石材料现有的不稳定性、较高的检测限和工作温度限制了尖晶石材料传感器的推广。本文综述了近年来尖晶石材料在气体传感器技术方面的研究进展,并结合以往的工作列举了常见的形态结构和材料敏化方法。
