| 摘 要： | 本文采用了静电纺丝方法制备了Cd掺杂的In2O3复合纳米纤维,通过X射线衍射(XRD)和扫描电镜(SEM)对纳米纤维材料进行了相关表征.研究了纯In2O3和另外两种不同Cd掺杂的In2O3纳米纤维材料制作的三种气敏元件对室内甲醛气体的气敏特性.结果表明在以摩尔比为1∶1复合时,用静电纺丝方法分别制备出In2O3和CdO纳米纤维后再按1∶1掺杂制作的气敏元件工作温度较低为280℃,在10 ppm时其响应可达13,响应/恢复时间为34 s/35 s;并且具有良好的选择性.

| Abstract: | In this paper pure In2O3, CdO and Cd-doped In2O3 nanofibers were synthesizd by electrispinning process. These nanofibers were then characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM）. We give correlational researches on three kinds of formaldehyde sensors based on pure In2O3 nanofibers and two other different Cd-doped In2O3 nanofibers. The result show that the sensors based on In2 O3 doped CdO nanofibers prepared by electrispinning exhibit high sensitivity and excel- lent selectivity; it＇s optimum working temperature is 280 ℃, the respone to 10 ppm formaldehyde was 13, respone/recovery time was 34 s/35 s. |
