PORPHYRIN-BASED CHEMISTRY FOR CARBON CAPTURE AND SEQUESTRATION

Abstract

Two major types of porphyrinic framework structures offer promise for carbon capture and sequestration (CCS) applications: 1) metal-organic frameworks (MOFs) in which the porphyrins serve as struts linking vertices comprised of metal -based clusters; 2) covalently-bonded organic frameworks (COFs) in which the porphyrins are bonded together as part of a continuous structure forming the framework. Porphyrinic MOFs synthesized to date offer a somewhat greater range of internal porosities and structural moieties, while porphyrinic COFs may have greater stability under a variety of ambient conditions. For successful CCS applications, several factors related to the chemistry are important, including sorptive capacity, adsorption/desorption kinetics and thermodynamics, cycling lifetime, environmental compatibility, and cost -effective schemes for efficient synthesis. The possibility of using porphyrinic materials in multiple roles, e.g. for capture, storage, and electrolytic CO2 reduction, is of special interest.
