The development of physisorptive materials for carbon dioxide capture has gained tremendous attention within recent years. An adsorption-based process that relies on microporous coordination polymers (MCPs) may offer a more cost-effective route to carbon sequestration, as opposed to amine scrubbing systems. MCPs of the M/DOBDC series (where DOBDC is 2,5-dioxido-1,4-benzenedicarboxylate, and M is Mg, Co, Ni, and Zn) have previously been shown to have significant capacities for carbon dioxide at low partial pressures, with Mg/DOBDC displaying 23.4 wt% carbon dioxide uptake at 0.1 atm and room temperature. Previous studies have mainly focused on static carbon dioxide sorption measurements or simple breakthrough experiments. The effect of water, a critical component of flue gas, on the carbon dioxide capacities of members of the M/DOBDC series, will be examined in this presentation. In addition methods for understanding structural evolution during exposure to water will be presented based on antimatter probes of porosity.
