摘要/Abstract:

Metal oxides are the most important semiconducting materials for chemiresistive gas sensors. In the past, to prepare metal oxides into various micro-/nano-particles can greatly increase their outer surface area and the amount of exposed sensing active sites, which has been broadly used to optimize the sensitivity of metal oxides at high temperature. However, this kind of "outer surface sensing" materials are still limited by low sensitivity at room temperature and poor selectivity. In this presentation, we show our study on developing metal-organic frameworks into a novel "inner surface sensing" materials for high-performance gas sensing. To optimize sensing performances, MOF 2D thin film, MOF-on-MOF heterojunction 2D thin film, and MOF 3D thin film have been prepared, respectively. As results, MOF thin film based "inner surface sensing" materials not only shows excellent performances in gas detection at room temperature, but also exhibits very attractive application in trace-vapor detection for solid analytes.
