【摘要】 <正>监控CO2浓度在农业生产、职业安全和医疗卫生等领域是不可或缺的[1]。现有的CO2传感器主要是基于电势测定法、固态电解质法和光学等方法。然而这些方法都存在一定的局限性,如基于溶液p H变化的电势测定法易受到挥发性酸气体和碱性气体的交叉干扰,固态支持电解质法需高温、耗能大且不能在易燃易爆的环境中使用,光学方法需要用到昂贵的大型仪器等等[2]。因此,新型的CO2更多还原

【Abstract】 Here, we present a novel CO2 gas sensor based on ionic liquid-induced electrochemiluminescence. It was found that purging an amine of luminol with a stream of CO2 gas could turn on the ECL emission of luminol, on the basis of which a selective and sensitive CO2 gas sensor was developed with a linear response over a wide CO2 concentration range from 0 to 100%, and a limit of detection of 80 ppm.更多还原
