摘要
丙酮是一种有毒有害的有机气体,广泛存在于工业生产及家居生活中,同时也是糖尿病的诊断物之一,因此准确实时的丙酮检测手段是安全生产和人体健康所迫切需要的。金属氧化物半导体气体传感器具有灵敏度高、成本低、可靠性高等优点,在有毒有害气体检测领域应用广泛。本文综述了近年来丙酮气敏传感材料的研究进展,对气敏材料的结构与形貌、气敏机理与改性手段等方面进行了介绍,分析了其研究现状以及未来的发展趋势。
Acetone is a toxic and harmful organic gas which is widely used in industrial production and household life,and it is also one of the diagnostics of diabetes.Therefore,accurate and real-time acetone detection methods is urgent for safety production and human health.Metal oxide semiconductor gas sensors have advantages of high sensitivity,low cost,and high reliability,and are widely used in the field of toxic and harmful gas detection.In this paper,the research progress of acetone gas-sensing materials in recent years is reviewed,the structure and morphology of gas-sensing materials,gas-sensing mechanism and modification methods are introduced,and its research status and future development trends are also analyzed.
