Preparation and Gas Sensing Performance of Highly Dispersed SnO2 Nanoparticles
摘要
Abstract
Highly dispersed SnO2 nanoparticels were synthesized at ambient conditions based on carbon microspheres,and the gas sensing properties of the material were studied systematically.The conductance responses of the material were measured by exposing it to ethanol gas (C2 H 5 OH).It was found that the sensor exhibited better sensing responses to ethanol gas than the commercial SnO2 at the working tempera-ture of 330 ℃.Furthermore,the gas sensor responses increased linearly with the increment of the gas con-centrations of ethanol in the range from 5×10 6 to 200×10 6 .关键词
