摘要
为了克服氧化锡/硫化亚锡(SnO_(2)/SnS)气敏传感器工作温度高、响应低及选择性差的缺陷,采用3%、5%及8%剂量的高价态Sb^(3+)掺杂,运用溶剂热法合成SnO_(2)/SnS蜂巢纳米片自组装花状微球气敏材料,对掺杂后的样品进行扫描电镜(SEM)表征发现,3%Sb^(3+)掺杂的SnO_(2)/SnS样品形貌较好.气敏性能测试结果显示,3%Sb^(3+)掺杂SnO_(2)/SnS样品在200℃时对三乙胺(TEA)选择性较好,具有较高的响应和低浓度检测极限.
In order to overcome the shortcomings of SnO_(2)/SnS gas sensor with high working temperature,low response and poor selectivity,honeycomb-like SnO_(2)/SnS nanosheets were synthesized by solvothermal method using 3%,5%and 8%Sb^(3+)doped.The samples were characterized by scanning electron microscopy(SEM),the samples doped by 3%Sb^(3+)was better than others.The gas sensitivity test results show that the 3%Sb^(3+)doped samples have a good selectivity to TEA at 200℃,and have a high response and low concentration detection limit.
