| 摘要: 采用水热-煅烧法制备Cd2SnO4，之后通过超声混合法得到一系列MoS2/Cd2SnO4复合材料。采用X射线衍射、扫描电子显微镜、X射线光电子能谱对Cd2SnO4和一系列MoS2/Cd2SnO4复合材料进行结构和形貌的表征。研究了MoS2掺杂量对于MoS2/Cd2SnO4复合材料的气敏性能影响。实验结果表明，当MoS2与Cd2SnO4的质量比为2.5%，MoS2/Cd2SnO4复合材料制备的气敏元件在170 ℃时对浓度为100 μL·L-1的甲醛气体的灵敏度为40.0，最低检测限为0.1 μL·L-1。 | |

| Abstract: Cd2SnO4 was prepared by hydrothermal-calcination method and a series of MoS2/Cd2SnO4 composite materials were prepared by ultrasonic mixing method. To analyze the structures and morphologies of the Cd2SnO4 and MoS2/Cd2SnO4 composite materials, X-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy were used. The effect of the doped amount of MoS2 on the gas sensing properties of MoS2/Cd2SnO4 composite materials was investigated. The results showed that when the mass ratio of MoS2 to Cd2SnO4 was 2.5%, the response of the gas sensor of MoS2/Cd2SnO4 composite material to 100 μL·L-1 formaldehyde vapor at 170℃ was 40.0 and the detection limit reached 0.1 μL·L-1. | |
