我们发展了一种简单的方法来合成纳米管或纳米线结构的氧化锡气敏元件。它是通过锡在多孔单壁碳纳米管（SWNTs）上的流变生长和热氧化（RGTO）来实现的。由此形成的纳米结构的形态和化学性质进行检查。研究了其电学特性和NO（x）气敏特性。该传感器具有小于100秒的快速响应时间和良好的恢复能力。观察到在200 ℃下对10 ppm浓度的23，400%的感测响应。
We develop a simple method to synthesize nano tube or wire structure of tin-oxide for gas sensor application. It is realized by the rheotaxial growth and thermal oxidation (RGTO) of tin on porous single-wall carbon nanotubes (SWNTs) as a template. The morphology and chemical property of thus formed nanostructures are examined. The electrical and NO(x) gas sensing properties are also investigated. The sensor exhibits a fast response time of less than 100 seconds and a good recovery. A sensing response of 23,400% to 10 ppm concentration at 200 degrees C is observed.
