摘　　要：为了研究硫锡化合物SnS_(x)(x=1,2)纳米片材料的气敏特性,以工艺简单的一步水热法制备SnS(硫化亚锡)及SnS_(2)(二硫化锡)纳米片气敏传感器;对SnS_(x)(x=1,2)纳米片样品进行扫描电镜(SEM)表征发现,SnS纳米片平均厚度在50 nm以下,SnS_(2)纳米片厚度在100 nm以上.气敏性能测试结果显示,SnS基传感器在190℃的工作温度下对50μL·L^(-1)的乙醇响应达到5.32,SnS_(2)纳米片传感器在160℃下对50μL·L^(-1)的三乙胺(TEA)的响应值为4.38,气敏性质差异大的主要原因是片层结构的不同.In order to study the gas sensitivity of the SnS_(x)(x=1,2)nanosheets,SnS and SnS_(2) nanosheets were prepared by one-step hydrothermal method.The scanning electron microscopy(SEM)of SnS_(x)(x=1,2)nanosheets displayed that the thickness of SnS nanosheets were less than 50 nm,and the thickness of SnS_(2) nanosheets were more than 100 nm.The results of experiment show that the responses of the SnS-based sensor toward 50μL·L^(-1) ethanol was 5.32 at 190℃,and the SnS_(2) sensor was 4.38 to 50μL·L^(-1) triethylamine(TEA)at 160℃.The difference of sensing properties can be ascribed to different laminar structures.
