摘　　要：利用压差交换气相输运复合的方法制备CuPc-SnO_(2)复合纳米多孔材料。通过扫描电子显微镜(SEM)及附带能谱仪(EDS)和傅里叶变换红外(FTIR)光谱仪对所得样品的微观形貌及元素成分进行表征,通过气敏分析系统测试其气敏性能。结果表明:该CuPc-SnO_(2)复合气体传感器对NO_(2)气体的灵敏度响应要明显优于纯的SnO_(2),在最佳工作温度120℃,传感器灵敏度与NO_(2)气体体积分数呈较好的线性关系,且对NO_(2)气体表现出良好的选择性。此外,通过原位霍尔测试系统对可能的气敏机理进行探讨。CuPc-SnO_(2)composite nanoporous materials are prepared by using differential pressure exchange gas phase transport composite method.Micro-morphology and element composition of the obtained samples are characterized by scanning electron microscope(SEM),energy dispersive spectroscopy(EDS)and Fourier transform infrared(FTIR)spectroscopy.The gas-sensitive properties are tested by gas-sensitive analysis system.The results show that the sensitivity response of the CuPc-SnO_(2)composite gas sensors to NO_(2)gas is prior to pure SnO_(2).At the optimum operating temperature of 120℃,the sensor sensitivity shows a good linear relationship with the volume fraction of NO_(2)gas,and exhibits a good selectivity to NO_(2)gas.In addition,the possible gas sensitive mechanism is investigated via in-situ Hall effect measurement system.
