甲/乙醇作为重要的新型能源已逐渐得到广泛使用,如甲醇燃料电池和甲醇汽油,利用乙醇制取化工原料、乙醇汽油等。甲/乙醇极易挥发,属于易燃易爆气体,因此,检测环境中的甲/乙醇气体浓度显得非常重要。综述了甲/乙醇气体传感器的研究进展,并重点在氧化物、聚合物和金属纳米粒子三种类型的甲/乙醇气体敏感材料进行了阐述。
As important new type energy sources,methanol/ethanol have been widely applied in many areas,such as methanol fuel cells and methanol fuel,preparation of chemicals using ethanol,ethanol gasoline,et al. Methanol/ethanol are very volatile and explosive. Therefore,it is very important to detect concentration of these gases in environment. Reviews on research progress of methanol/ethanol gas sensors and three types of methanol/ethanol gas sensitive materials( oxides,polymers and metal nanoparticles)are described.
