An amine functionalized zirconium metal–organic framework as an effective chemiresistive sensor for acidic gases†
Abstract
Pore surface functionalization of a metal–organic framework (MOF) with an amine moiety has turned an innocent MOF into a chemiresistive sensor for acidic gases. The Zr-NH2-benzenedicarboxylate MOF (NH2-UiO-66) proved to perform as an efficient and stable chemiresistive sensor for SO2, NO2 and CO2 at low concentrations and an operating temperature of 150 °C.
