| 摘 要： | 以金属铟粒为铟源制备硝酸铟溶液,采用水热法合成纳米In<,2>O<,3>,粉体,并通过贵金属Pd和Ag掺杂对In<,2>O<,3>粉体进行修饰.利用X射线衍射仪(XRD),比表面积测试仪(BET)等分析手段对材料进行表征,并且研究了气敏性能.结果表明:制得的In<,2>O<,3>粉体属于立方晶型,晶粒度为25.08 nm.In<,2>O<,3>气敏元件对丙酮、乙醇汽油及H<,2>S气体有较高的灵敏度和较好的响应恢复特性.Pd掺杂In<,2>O<,3>对ψ(乙醇汽油)为100×10<'-6>和ψ(H<,2>S)为50×10<'-6>的灵敏度分别高达36.70和87.96. |
