Abstract
Results from in situ experiments are presented to correlate carbon capture with dynamic structural changes in two flexible metal-organic framework (MOF) materials: porous coordination polymers (PCPs) exhibiting promising carbon dioxide adsorption/desorption properties. These properties arise from different internal ligand linker arrangements. Specifically, adsorption/desorption gas isotherm measurements are compared with in situ small-angle neutron scattering (SANS) and diffraction measurements of the associated structural changes, and complimentary wide-angle neutron and X-ray diffraction measurements. The prospects for improving each systems carbon capture functionality, including its selectivity for adsorbing CO2 from gas mixtures, are discussed with reference to a potential materials-by-design approach.
