Abstract
The research focuses on chemiresistive sensing of carbon dioxide (CO₂) using a series of two-dimensional (2D) conductive metal-organic frameworks (MOFs) with amine-based linkers. The 2D MOFs studied here show carbon dioxide sensitivity at concentrations as low as 1000 ppm. The identity of both the metal and ligand affects sensing performance in terms of sensitivity, reversibility, selectivity, and response to moisture. Experimental and computational data indicate that the amine groups of the ligands play a key role in the CO₂ sensing mechanism. This work represents the first use of electrically conductive MOFs for CO₂ sensing, and demonstrates a combination of sensitivity and selectivity that is promising for practical applications.
