| 1 | 金属氧化物半导体气体传感器应用现状和发展情况显示文摘金属氧化物气体传感器在社会经济发展中具有不可代替的重要作用,是各国研究者重点关注对象之一.目前,对金属氧化物气敏性能改善的研究主要集中在化学组分优化和微观结构优化设计两个方向,并制备出了具有各种微观结构形貌的气敏性能良好的新型金属氧化物基半导体材料.但能在低温、常温工作的高性能金属氧化物气敏材料仍不能满足应用需求,这给科研工作者们带来极大的挑战和机遇. | 陈祥铭 杨贵钦 赵海茹 涂晔 | 2020 | 玉溪师范学院学报2020，36，6： | 4 |
| 2 | Gas sensors based on TiO_(2) nanostructured materials for the detection of hazardous gases: A review显示文摘Hazardous gases have been strongly associated with being a detriment to human life within the environment The development of a reliable gas sensor with high response and selectivity is of great signifcance for detecting different hazardous gases.TiO_(2) nanomaterials are promising candidates with great potential and excellent per-formance in gas sensor applications,such as hydrogen,acetone,ammonia,and ethanol detection.This review begins with a detailed discussion of the di ferent dimensional morphologies of TiO_(2),whitch affect the gas sensing performance of TiO_(2) sensors.The diverse morphologies of TiO_(2) can easily be tuned by regulating the manufacturing conditions.Meanwhile,they exhibit unique characteristics for detecting gases,including large specific suface area,superior elecron tr ansport rates,extraordinary pemmeability,and active reaction sites,which offer new opportunities to improve the gas sensing properties.In addition,a variety of efforts have been made to functional TiO_(2) nanomaterials to further enhance sensing properties,including TiO_(2)-based composites and light-assisted gas sensors.The enhanced gas sensing mechanisms of multi-component composite nano-materials based on TiO_(2) include loaded noble metals,doped elements,constructed heterojunctions,and com-pounded with other functional materials.Finally,several studies have been summarized to demonstate the compar ative sensing properties of TiO_(2)-based gas sensors. | Xu Tian Xiuxiu Cui Tingrun Lai Jie Ren Zhichao Yang Mingjing Xiao Bingsen Wang Xuechun Xiao Yude Wang | 2021 | Nano Materials Science2021，3，4： | 1 |
