| 摘 要： | 采用微反应器–气相色谱联用装置和气敏性能测试设备,评价了不同掺杂的In2O3材料对异丁烷的催化及气敏性能。研究表明:掺杂贵金属(Pd、Pt、Au等)可大幅度提高材料对异丁烷的催化活性,灵敏度也由2.99提高到4以上;而掺杂碱性金属氧化物则降低了材料的催化活性和灵敏度。材料的气敏性能和催化性能存在密切的关系。并浅析了材料的敏感机理。

| Abstract: | The catalytic property and gas sensitivity of different dopant indium oxide to iso-butane were investigated by micro-reactor and gas chromatography as well as gas sensing property testing apparatus. The results show that the sensitivity of indium oxide doping noble metal to iso-butane is increased from 2.99 to above 4, for the dopant could improve the catalytic property of indium oxide. The sensitivity of indium oxide doping basic metal oxide to iso-butane is decreased, because these materials decreased the catalytic activity. Gas-sensing performance is intrinsically depended on the catalytic property. Gas-sensing mechanism of indium oxide is also revealed briefly. |
