| 摘 要： | 在ＺｎＯ基体材料中添加稀土金属氧化物ＣｅＯ２制成了抗干扰的Ｈ２Ｓ气体传感器，研究了其对Ｈ２Ｓ气的响应特性，发现在１０ｐｐｍ的Ｈ２Ｓ气中，灵敏度可高达２０倍、且响应迅速，而对几种干扰气ＣＯ（１００ｐｐｍ），ＣＨ４（３０００ｐｐｍ），ｉ－Ｃ４Ｈ１０（１００ｐｐｍ）响应很小．

| Abstract: | Interference-free hydrogen sulfide(H2S)gas sensors have been fabricated byadding cerium oxide to zinc oxide powder.Their response characters to H2S gas havebeen tested.It is found that their sensitivities to 10 ppm H2S gas can be as high as twen-ty,and they response rapidly, However,they response very little to interfent gasessush as CO(10ppm),CH4(3000 ppm),i-C4H10(100 ppm). |
