Direct visualisation of carbon dioxide adsorption in gate-opening zeolitic imidazolate framework ZIF-7

The crystal structures of zeolitic imidazolate framework 7 (ZIF-7) under various CO 2 pressures were studied by high-resolution neutron powder diffraction. CO 2 adsorption in ZIF-7 is visualised and demonstrated to be primarily controlled by the benzimidazolate ligands via a gate-opening mechanism....

Zusammenfassung:The crystal structures of zeolitic imidazolate framework 7 (ZIF-7) under various CO 2 pressures were studied by high-resolution neutron powder diffraction. CO 2 adsorption in ZIF-7 is visualised and demonstrated to be primarily controlled by the benzimidazolate ligands via a gate-opening mechanism. Our results highlight the importance of pressure on the CO 2 adsorption and the related structural framework responses in ZIF-7.
