摘要

采用溶胶-凝胶法成功合成了SnO2纳米颗粒结构，并开发了用于丙酮气体检测的纳米颗粒结构。采用x射线衍射(XRD)和扫描电镜(SEM)对颗粒的形貌和结构进行了表征。研究结果表明，SnO2纳米颗粒结构可作为丙酮气体传感器，具有快速的响应时间，是设计和制造具有良好气体传感性能的丙酮气体传感器的理想材料。提出了可能的气敏机理。

Fast response acetone-sensing properties of SnO2 nanoparticles prepared by the sol-gel method

SnO2 nanoparticle architectures were successfully synthesized using a sol-gel method and developed for acetone gas detection. The morphology and structure of the particles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The SnO2 nanoparticle architectures were configured as high-performance sensors to detect acetone and showed a very fast response time ( nanoparticles should be promising candidates for designing and fabricating acetone gas sensors with good gas sensing performance. The possible gas sensing mechanism is also presented.
