Y沸石改善SnO2气体传感器性能的研究
Improvement of SnO2 Gas Sensing Properties by Using Y-Zeolite
摘要
Abstract
In order to improve the sensitivity of the gas sensor,the SnO2 gas sensor was modified with Y-zeolite by coating Y-zeolite on the surface of SnO2 and mixing SnO2 and Y-zeolite,respectively. The structure andsurface prop-erties of the composites made by mixing SnO2 and Y-zeolite were characterized by using X-ray diffraction( XRD) and scanning electron microscopy( SEM) ,respectively. Some VOC gases were tested by using these two types of sensors. The results show that compared with pure SnO2 gas sensor,the response value of the sensor made of mixing SnO2 and Y-zeoliteto acetone increases, and to other gases are not change obviously. The response value of the sensor made of coating method increase to acetone,meanwhile decrease to ethanol vapor,indicating an inhibit act to etha-nol.The mechanism of Y-zeoliteimprove the SnO2 gas sensing properties was briefly analyzed.关键词
