摘要

为了改善传感器的气敏性能

采用溶胶—凝胶法合成了介孔SnO2

并研究了其气敏性能。研究表明:与纳米SnO2相比

介孔SnO2气体传感器具有较高的酒精、二甲苯响应

在100～150℃对甲醛的响应也大大提升。在100～150℃

干扰气体为甲苯和二甲苯时

介孔SnO2表现远远优越于纳米SnO2的酒精选择性。在100

150

350℃

干扰气体为甲苯时

介孔SnO2也具有优越的甲醛选择性。介孔SnO2的响应时间较短

但恢复时间较长。

Abstract

In order to improve the performance of gas sensors

mesoporous SnO2 is prepared using sol-gel method

and its gas sensing properties are also studied.The results indicate that mesoporous SnO2 gas sensor has better responses to ethanol and xylol and greatly enhance the response to toluene at 100

50 ℃

compared with nano-SnO2.The mesoporous SnO2 sensors show far better ethanol selectivity than nano-SnO2 when the interferential gases are toluene and xylol at 100

50 ℃.Superior toluene selectivity of mesoporous SnO2 sensors are exhibited when toluene as interferential gas at 100

150

350 ℃.The response time of mesoporous SnO2 sensor is short but recovery time is relatively long.
