| 摘 要： | 与零维、二维和三维纳米材料相比,一维纳米材料具有优异的气敏性能。以Zn(NO_3)_2·6H_2O和Fe(NO_3)_3·9H_2O为原料通过静电纺丝的方法制备了一维铁酸锌纳米纤维。利用TG-DSC分析了材料的前驱体,用XRD、SEM、TEM、FT-IR、BET和XPS对材料进行了表征,并且对材料的气敏性能进行了研究。结果表明,在煅烧温度为500℃下获得的材料呈现出纳米纤维的形貌;基于500℃下获得的铁酸锌纳米纤维的元件,在工作温度为190℃下对丙酮表现出较高灵敏度和高选择性,S_(1000μL/L丙酮)/S_(1000μL/L乙醇)=8;当丙酮浓度低至1μL/L时,灵敏度仍能达到1.1。

| Abstract: | Compared with zero dimensional, two dimensional and three dimensional nano-materials, one dimensional nano-materials have superior gas sensing properties. In this paper, one dimensional ZnFe2O4 nano-fibers were prepared via electrospinning method using Zn (NO3)2? 6H2O and Fe (NO3)3? 9H2O as raw materials. The precursor was analyzed by TG-DSC, and the as-prepared samples were characterized by XRD, SEM, TEM, FTIR, nitrogen adsorption and XPS, respectively. The gas sensing properties of the as-prepared samples were investigated. The results showed that ZnFe2O4 prepared at 500oC exhibited nano-fiber morphology; it was revealed that the sensor device based on ZnFe2O4 nanofibers prepared at 500?C exhibited excellent selectivity toward acetone at the operating temperature of 190oC, the ratio of S1000 ppm acetone to S1000 ppm ethanol reached 8; when the concentration of acetone was as low as 1 ppm, the response was still able to reach 1.1. |
