Low concentration gas detection, rapid response time and low working temperature are anticipated for a varied range of toxic gas detection applications. Conversely, the existing gas sensors suffer mostly from a high working temperature along with a slow response at low concentrations of analytes. Here, we report an ultrasensitive flexible nanostructured ZnFeO ( = 0.1, 0.5 and 0.9) based chemiresistive sensor for nitrogen dioxide (NO) detection. We evince that the prepared flexible sensor ZnFeO has detection potential as low as 5 ppm at a working temperature of 90 °C in a short phase. Further, the ZnFeO sensor exhibits excellent selectivity, stability and repeatability. The optimized sensor sensing characteristics can be helpful in tremendous development of foldable mobile devices for environmental monitoring, protection and control.
对于各种有毒气体检测应用，人们期望实现低浓度气体检测、快速响应时间和低工作温度。相反，现有的气体传感器大多存在工作温度高以及在低浓度分析物下响应缓慢的问题。在此，我们报道了一种基于超灵敏柔性纳米结构ZnFeO（= 0.1、0.5和0.9）的化学电阻传感器，用于检测二氧化氮（NO）。我们证明，制备的柔性传感器ZnFeO在90°C的工作温度下，在短时间内具有低至5 ppm的检测潜力。此外，ZnFeO传感器表现出优异的选择性、稳定性和可重复性。优化后的传感器传感特性有助于可折叠移动设备在环境监测、保护和控制方面的巨大发展。
