| 摘要: 高灵敏和选择性的气体传感器对于实时监测大气中有毒有害气体和早期的疾病诊断具有重要的意义。目前，传统的气敏材料仍然存在着许多问题亟待解决，例如：选择性差、检测极限不够低、使用寿命短等。作为一种多孔的配位聚合物，金属有机框架材料(MOFs)由于其超高的比表面积和较大的孔隙率在气体传感器领域已经得到广泛的应用。利用 MOFs自身或者由它们衍生的不同纳米结构的金属氧化物可以提升气体传感器的灵敏度和选择性，为制备新型高性能的气体传感器提供了新的思路和方向。本文结合金属氧化物半导体(MOS)的气敏机理，综述了不同结构的 MOFs及其衍生的金属氧化物在电阻式气体传感器领域的研究进展，并对其应用前景和发展方向作出了展望。 |

| Abstract: Highly sensitive and selective gas sensors are of great significance for real-time monitoring of toxic and harmful gases in the air and early diagnosis of diseases. At present, there are still many problems to be solved urgently for traditional gas-sensing materials. For example, the selectivity is poor and the detection limit, as well as the service life, is insufficient. Metal-organic frameworks (MOFs), as a kind of porous coordination polymers, have been widely used in the field of gas sensors due to their ultra-high specific surface areas and large porosities. MOFs and their derived metal oxides with different nanostructures can improve the sensitivity and selectivity of gas sensors. This provides new ideas and directions for preparing new high-performance gas sensors. Combining the gas sensing mechanism of metal oxide semiconductors (MOS), this article reviews the research progress of MOFs with different nanostructures and their derived metal oxides in the field of resistive gas sensors and prospects their applications and development directions. |
