摘要: 在本工作中，我们利用水热法合成了SnO2纳米片并研究了其乙醇气敏性能。材料表征显示所合成的样品是四方相SnO2，结晶性良好，表面形貌是纳米片状，厚度仅有约10 nm。在240˚C的最佳工作温度下，SnO2纳米片对200 ppm乙醇的灵敏度达到36.5，而响应时间和恢复时间分别短至6 s和5 s。优异的气敏性能预示了SnO2纳米片在乙醇蒸汽检测方面巨大的应用潜力。
Abstract: In this work, we synthesized SnO2 nanoplates using a hydrothermal method and then studied their ethanol sensing performance. The material characterization shows that as-synthesized sample is tetragonal SnO2 with good crystallinity, and a surface morphology of nanoplates with a thickness of only about 20 nm. At the optimal operating temperature of 240˚C, the sensitivity of SnO2 nanoplates to 200 ppm ethanol reached 36.5, while the response time and recovery time were as short as 6 s and 5 s, respectively. The excellent gas sensing performance indicates the enormous application potential of SnO2 nanoplates in ethanol vapor detection.
