| 摘 要： | 制备了一种针对CO的石墨烯负载氯化钯的气敏传感材料。扫描电镜分析表明,所制备的材料具有明显的2种不同的形貌:二维薄片状和三维颗粒状;透射电镜和高分辨透射电镜照片以及选区电子衍射花样显示,石墨烯负载的氯化钯材料颗粒粒度小于10nm,为单晶材料。性能测试分析表明,以该材料制备的电极材料制作的气敏器件,对CO气体检测下限为0.1μg·g~(-1)水平,敏感度高,灵敏度为63.34 mV/(μg·g~(-1)),该传感器的响应时间为8～9 s。

| Abstract: | The novel gas-sensing material of Graphene-loaded PdCl2 was prepared successfully by the facile method without the use of any additive or organic active agent. The morphology of the as-prepared electrode material was consisted of two different morphologies: thin sheets and small particles with the size of several nanometers. In order to investigate its gas properties, it was used to fabricate a whole solid-state planar electrochemical carbon monoxide sensor. The results showed that the sensor has a practical-use level: response time, 10 s; detect of limit, 100 ppb; sensitivity, 63.34 mV/ppm. |
