    摘要:

    本文制備了一種針對CO的石墨烯負(fù)載氯化鈀的氣敏傳感材料。掃描電鏡分析表明：材料由明顯的兩種不同形貌材料構(gòu)成：二維薄片狀和三位顆粒狀；透射電鏡和高分辨透射電鏡照片以及選取電子衍射照片顯示,石墨烯負(fù)載的氯化鈀材料顆粒粒度小于10納米,為單晶材料。性能測試分析表明,以該材料制備成電極材料制作的氣敏器件,對CO氣體檢測下限為100ppb水平,敏感度高,靈敏度為63.34 mV/ppm,該傳感器的響應(yīng)時(shí)間大約為8~9秒。

    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.
