摘要: 采用静电纺丝法制备了4种不同类型ZnO纳米纤维，均匀涂覆于刻有叉指铂金电极的硅基底表面形成敏感薄膜，设计了一种薄膜型挥发性有机物传感器。采用X射线衍射仪、扫描电子显微镜和X-射线光电子能谱仪，表征了敏感薄膜的相组成和微观形貌，分析了敏感薄膜的气敏机理和电化学特性，测试了传感器对甲苯、甲醛、丙酮和乙醇的灵敏特性、温度特性、动态响应和选择稳定性。结果表明，当温度为200℃，浓度为30 μg/m³时，传感器（Pd@SnO₂-ZnO）对甲苯、甲醛、丙酮和乙醇的响应最大，分别为70.1、56、34.9和13.8，动态响应/恢复时间分别为4.9/9.6、13.8/12.2、20.2/17.6和29.6/39.6 s，检出限分别为1.0、3.0、4.0和5.0 μg/m³。连续使用1200 h后，传感器对甲苯、甲醛、丙酮和乙醇响应衰减量分别为0.21、0.30、0.22和0.10。

Abstract: ZnO, SnO₂-ZnO, Pd@ZnO and Pd@SnO₂-ZnO composite nanofibers were synthesized by electrospinning method. On the basis of this, a new film-type volatile organic compounds (VOCs) sensor was designed by transferring the composite nanofibers above onto silicon substrate with platinum-inter digital electrodes by dip-coating method. Multiple characterizations were employed to investigate the crystal structure, composition, morphology, and bonding states of the composite nanofibers. The characteristic tests of Pd@SnO₂-ZnO sensor were carried out in gas sensor test system. The obtained results clearly demonstrated that Pd@SnO₂-ZnO nanofibers exhibited significantly enhanced volatile organic compounds sensing performance compared with other nanofibers. When the operating temperature was 200℃ and the target gas concentration was 30 μg/m³, the responses of Pd@SnO₂-ZnO sensor toward different volatile organic components including toluene, formaldehyde, acetone and ethanol were 70.1, 56, 34.9 and 13.8, respectively. Dynamic response time and recover time of Pd@SnO₂-ZnO sensor were 4.9/9.6, 13.8/12.2, 20.2/17.6 and 29.6/39.6 s respectively, which was much higher than that of ZnO nanofibers. The enhanced VOC sensing properties of Pd@SnO₂-ZnO composite nanofibers could be attributed to the electronic and chemical sensitizations of Pd and the junction formation at the interface of SnO₂ and ZnO.
