摘要: This work concerns with metal oxide (MOX) gas sensors based on nanowires and thin films. We focus chemical warfare agents (CWAs) detection to compare these materials from the functional point-of-view. different chemicals including simulants for Sarin nerve agents, vescicant gases, cyanide analytes such as ethanol, acetone, ammonia, carbon monoxide that can be produced by everyday activities causing false alarms. Explorative data analysis has been used demonstrate sensing performances of Within chosen application, our reveal introduction inside array composed films improve its capability. Cyanide have detected at concentrations close 1 ppm, lower than Immediately Dangerous Life Health (IDLH) value respective agent. Higher sensitivity obtained which or even 100 ppb. Results suitability proposed selectively detect CWA respect some compounds activities.
