Up to 1 bar pressure (at 298 K), microporous MOF with open metal sites HKUST-1 shows the best performance in SF6 adsorption and microporous Zn4O(dmcpz)3 in CF4 adsorption. At high pressure, mesoporous MIL-101 and DUT-9 have the highest storage capacities for both gases among the MOFs investigated.enMetal-organic frameworkshigh pressure adsorptionsulfur hexafluoridecarbon tetrafluoridegreenhouse gas541journal article
