A 3D cobalt corrole-based Zr-MOF for the selective adsorption of carbon monoxide

Abstract

Two 3D MOFs based on triphenylcorrole and its cobalt-metalated analog (CoCorr-MOF) are presented. They show a hexagonal structure, a homogeneous particle size, and 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), demonstrating a CO chemisorption capacity of 7.2 cm³ g⁻¹ with high selectivity.
