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。The novel gas-sensing material of graphene-loaded PdCl2 was prepared by the facile method without the use of any additive or organic active agent.The as-prepared electrode material is consisted of two different morphologies:thin sheets and small particles with the size of several nanometers.In order to investigate its gas sensing properties,it was used to fabricate a whole solid-state planar electrochemical carbon monoxide sensor.The results show that the sensor has a practical-use level:response time is 8~9 s;detect of limit is 0.1μg·g^(-1);sensitivity is 63.34 m V/(μg·g^(-1)).
