Abstract
The invention is directed to a chemically robust, highly-selective, low power sensor that can be used for the direct electrical detection of mixed gases. In particular, metal-organic frameworks (MOFs) offer exceptional chemical and structural tunability as mixed-gas capture materials. As an example of the invention, the influence of interfering gases on trace NOdetection in a simulated flue gas stream was investigated. The unique interaction of NOwith the MOF's metal center leads to orders of magnitude decrease in MOF resistance. More broadly, the coadsorption of specific gases (e.g., HO, SO) can be beneficial to the electrical detection of the target gas (e.g., NO), and careful electrical measurements can discern their presence independent of the target gas.
