Study on Gas Sensing Performance of CuO-Doped SnO2 Nanoflower Hydrogen Sulfide Sensor
为了提高SnO2 基气体传感器在H2S气体检测方面的响应,并降低其工作温度,结合水热法和浸渍沉淀法成功制备出基于CuO-SnO2 纳米花复合物的H2S气体传感器.通过SEM、TEM、XRD、XPS等方式对敏感材料进行表征,并对不同浓度的H2S气体进行了气敏测试.实验结果表明,纳米CuO颗粒的掺入大大提升了传感器的响应,并降低了工作温度.其中,10 mol%CuO-SnO2(10CS)传感器的响应提升最大,对于50×10-6 H2S其响应高达23 286.2,是纯SnO2 传感器的366倍;其最佳工作温度相对于纯SnO2 传感也有大幅降低.此外,10CS传感器还展现出优异的重复性、稳定性和选择性,具备较好的实际应用潜力.
In order to improve the response of SnO2 based gas sensor in H2 S gas detection and reduce its operating temperature,the H2 S gas sensor based on CuO-SnO2 nanoflower composite is successfully prepared by using hydrothermal method and impregnation precipita-tion method.The sensitive materials are characterized by SEM,TEM,XRD,and XPS,and the gas sensitivity for H2 S at different concen-trations is tested.The experimental results show that the incorporation of nano CuO particles greatly improves the response of the sensor and reduces the operating temperature.Among all the samples,the response improvement of the 10 mol%CuO-SnO2(10CS)sensor is the highest,with a response of 23 286.2 for 50×10-6 H2 S,which is 366 times higher than that of pure SnO2 sensors.Its optimal operat-ing temperature is significantly reduced compared to pure SnO2sensing.In addition,the 10CS sensor also exhibits excellent repeatabili-ty,stability,and selectivity,with good practical application potential.
