本文报道了一种电流型银离子玻璃固态电解质 NO2 气敏传感器 ,该传感器可在室温下工作 ;响应及恢复速度较快 ;能检测低达 0 .5ppm的 NO2 气体浓度 ;在 0～ 10 0 ppm范围内与被测气体浓度具有线性关系 ;基本消除了记忆效应且不受空气及氧气的影响。本工作为研制和开发小型、廉价、适用于工业废气和汽车尾气等污染源的在线实时检测 NO2 的仪器奠定了基础 This paper reports a current-type silver ion glass solid-state electrolyte NO2 gas sensor that operates at room temperature with fast response and recovery, detects NO2 gas concentrations as low as 0.5 ppm, There is a linear relationship between the concentration and the measured gas concentration; the basic elimination of the memory effect and is not affected by air and oxygen. This work lays the foundation for the development and development of small-scale, low-cost, on-line real-time detection of NO2 instruments for industrial exhaust gas and automobile exhaust and other pollution sources
