摘要
研究了磷钨酸二取代铵盐和磺化杯芳烃复合电解质的组成对氢和一氧化碳固态电位传感器特性的影响,包括它们在空气中的同时检测。CO传感器的响应时间与复合电解质的组成无关,对于0.1 vol %,其值约为2分钟。该研究还观察到两种类型的开路电压,这取决于电解质成分。传感器显示了对CO的选择性,在浓度与H2浓度相当的H2 - CO -空气中检测到它。
Acid Ammonium Salt of 12-Phosphotungstic Acid and Calixarene Composite Solid Electrolytes for Potentiometric H2 and CO Sensors
The work is focused on the analysis the impact of the composition of a composite electrolyte comprising a disubstituted ammonium salt of phosphotungstic acid and sulfonated calixarene on the characteristics of solid-state potentiometric sensors for hydrogen and carbon monoxide, including their simultaneous detection in air. The response time of the CO sensors is shown to be independent of the composition of the composite electrolyte, with a value of approximately two minutes for 0.1 vol %. The study also observed two types of open circuit voltage, depending on the electrolyte composition. The sensors demonstrated selectivity for CO, detecting it in the H2–CO–air atmosphere at concentrations comparable to H2 concentrations.
