| 摘 要： | 采用水热法制备了一系列具有不同碳量子点(GQDs)含量的MoO3?GQDs纳米复合材料,利用X射线衍射、扫描电子显微镜、透射电子显微镜、FTIR等对MoO3?GQDs复合材料进行了表征,研究了其气敏性能。结果表明,复合材料中GQDs的含量对MoO3?GQDs复合材料的气敏响应和选择性有显著影响。MoO3?GQDs纳米复合材料(S?6,GQDs悬浮液的含量为6 mL)传感器在230℃时对三甲胺(TMA)表现出高的气敏响应和好的气敏选择性;该传感器对1000μL·L^-1 TMA的响应为74.08;对1000μL·L^-1 TMA的响应时间和恢复时间分别为73和34 s;S?6复合材料气敏传感器在230℃时可以检测到1μL·L^-1的TMA。

| Abstract: | A series of MoO3?GQDs nano?composites with different amounts of graphene quantum dots(GQDs)were prepared by the hydrothermal method.The as?prepared samples were characterized by X?ray diffraction,Scanning electron microscope,Transmission electron microscope,FTIR and so on.The gas sensing properties of MoO3?GQDs were investigated.It was found that the amount of GQDs in the composites had a great influence on the gas response and gas sensing selectivity of the nano?composites.The sensor based on the MoO3?GQDs nano?composite(S?6,the amount of GQDs suspension was 6.0 mL)showed high response and good gas sensing selectivity to TMA at 230℃;the response of the sensor to 1000μL·L^-1 TMA was 74.08;the response time and recovery time to 1000μL·L^-1 TMA were 73 and 34 s,respectively;the sensor based on MoO3?GQDs(S?6)composite could detect 1μL·L^-1 TMA vapor at 230℃. |
