摘要
采用水热-煅烧法制备Cd_(2)Sn O_(4),之后通过超声混合法得到一系列Mo S_(2)/Cd_(2)Sn O_(4)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Cd_(2)Sn O_(4)和一系列Mo S_(2)/Cd_(2)Sn O_(4)复合材料进行结构和形貌的表征。研究了Mo S_(2)掺杂量对于Mo S_(2)/Cd_(2)Sn O_(4)复合材料的气敏性能影响。实验结果表明,当Mo S_(2)与Cd_(2)Sn O_(4)的质量比为2.5%,Mo S_(2)/Cd_(2)Sn O_(4)复合材料制备的气敏元件在170℃时对浓度为100μL·L^(-1)的甲醛气体的灵敏度为40.0,最低检测限为0.1μL·L^(-1)。
Cd_(2)Sn O_(4)was prepared by hydrothermal-calcination method and a series of Mo S_(2)/Cd_(2)Sn O_(4)composite materials were prepared by ultrasonic mixing method.To analyze the structures and morphologies of the Cd_(2)Sn O_(4)and Mo S_(2)/Cd_(2)Sn O_(4)composite materials,X-ray diffraction,scanning electron microscopy,and X-ray photoelectron spectroscopy were used.The effect of the doped amount of Mo S_(2)on the gas sensing properties of Mo S_(2)/Cd_(2)Sn O_(4)composite materials was investigated.The results showed that when the mass ratio of Mo S_(2)to Cd_(2)Sn O_(4)was 2.5%,the response of the gas sensor of Mo S_(2)/Cd_(2)Sn O_(4)composite material to 100μL·L^(-1)formaldehyde vapor at 170℃was40.0 and the detection limit reached 0.1μL·L^(-1).
