Abstract

This study is an investigation of high-humidity aging effects on the total volatile organic compound (T-VOC) gas-sensing properties of platinum, palladium, and gold-loaded tin oxide (Pt,Pd,Au/SnO(2)) thick films. The sensor responses of the high-humidity aged Pt,Pd,Au/SnO(2), a non-aged Pt,Pd,Au/SnO(2), and a high-humidity aged Pt/SnO(2) to T-VOC test gas have been measured. The high-humidity aging is an effective treatment for resistance to humidity change for the Pt,Pd,Au/SnO(2) but not effective for the Pt/SnO(2). The mechanism of the high-humidity aging effects is discussed based on the change of surface state of the SnO(2) particles.

摘要

本研究探讨了高湿度老化对负载铂、钯和金的氧化锡(Pt、Pd、Au/SnO2)厚膜的总挥发性有机化合物(T-VOC)气体传感性能的影响。测量了高湿度老化的 Pt、Pd、Au/SnO2、未经老化的 Pt、Pd、Au/SnO2 和高湿度老化的 Pt/SnO2 对 T-VOC 测试气体的传感器响应。高湿度老化是一种有效处理 Pt、Pd、Au/SnO2 对湿度变化的电阻的方法,但对 Pt/SnO2 无效。基于 SnO2 颗粒表面状态的变化,讨论了高湿度老化效应的机制。
