摘　　要：采用水热法合成了锡酸锌(Zn_2SnO_4)多面体,通过X射线衍射和扫描电子显微镜对其物相和形貌进行了表征,并测试了基于Zn_2SnO_4多面体所制得的气敏元件的气敏性能。研究结果表明,气敏元件对乙醇具有良好的选择性,在300℃的最佳工作温度下,气敏元件对浓度为1000mg/L的乙醇气体的灵敏度达到19.2。Zn_2SnO_4 polyhedrons were synthesized by hydrothermal method.The phase and morphology were characterized by XRD and SEM.The sensitivity of gas sensor based on Zn_2SnO_4 polyhedrons was detected.The experimental results showed that the sensor selectivity to ethanol was very well.The sensitivity of sensor to 1000 mg/L ethanol reached 19.2 at 300℃.
