3D Cobalt Corrole-based Zr-MOF for the Selective Adsorption of Carbon Monoxide

Abstract

Two 3D MOFs based on a triphenylcorrole and their cobalt-metalated analogs (CoCorr-MOF) are presented. They show a hexagonal morphology, homogeneous particles size, and a microporosity with a specific area of 390 and 304 m² g-1, respectively. The CoCorr-MOF presents a better affinity for CO than for other interferents (N2, CO2 and O2). It demonstrates a CO sorption capacity of 7.2 cm3 g-1 with high selectivity.
