Direct visualisation of carbon dioxide adsorption in gate-opening zeolitic imidazolate framework ZIF-7
Journal of Materials Chemistry A, 2014•pubs.rsc.org
The crystal structures of zeolitic imidazolate framework 7 (ZIF-7) under various CO2
pressures were studied by high-resolution neutron powder diffraction. CO2 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 CO2
adsorption and the related structural framework responses in ZIF-7.
