| 摘 要： | 为了能够对低体积分数的氢气进行灵敏探测,提高氢气生产、使用、运输、存储的安全性,通过热蒸发SnO2和活性炭的混合粉末的自组装方式直接在Cr-Au梳状交叉电极上制备了一层SnO2纳米线气敏层,构成了SnO2纳米线气体传感器。经测试,发现此传感器对于体积分数范围为10×10-6~500×10-6的氢气具有良好的探测灵敏度。

| Abstract: | Hydrogen sensors are fabricated by self-assembled method that the SnO2nanowires sensing layer are directly synthesized on the Cr-Au comb-shape interdigitating electrodes by thermal evaporation of SnO2and active carbon mixture powders for decreasing the ratio of explosion and improving the safe of production,usage,transport and storage for hydrogen by investing the hydrogen with lower volume fraction.The sensors have highly gas sensitive property for the rather lower hydrogen volume fraction at the range of 10×10-6~500×10-6. |
