摘要
采用水热法制备了CdSnO_3纳米微粒,通过X射线衍射和透射电镜分别对CdSnO_3的物相和形貌进行了表征。结果发现,样品为梭形和不规则的小颗粒。对基于CdSnO_3纳米微粒所制作的气敏元件在乙醇、三乙胺和苯中的气敏性能进行了研究。测试结果表明,在340℃的最佳工作温度下,元件对1000 mg/L的三乙胺的灵敏度达38.4,响应和恢复时间分别为15 s和11 s。
CdSnO3 nanopaticles were synthesized by hydrothermal method. The phase and morphology were characterized by XRD and TEM. The results showed that samples were spindle - like structure and irregular particles. The gas sensing properties of sensor based on CdSnO3 nanopaticles for different gases such as ethanol, triethylamine, benzene were researched. The measured results indicated that the sensitivity of the sensor to 1000 mg/L triethylamine reached 38.4 at the best operating temperature of 340℃, and the response and recover time was 15 s and 11 s, respectively.
