Abstract
High pressure excess adsorption isotherms of sulfur hexafluoride (SF 6) and tetrafluoromethane (CF 4) on metal-organic frameworks Cu 3(btc) 2 (HKUST-1, btc - benzene-1,3,5- tricarboxylate), Fe 3FO(H 2O) 2(btc) 3 (MIL-100), Cr 3F(H 2O) 2O(1,4-bdc) 3 (MIL-101, 1,4-bdc - 1,4-benzenedicarboxylate), Co 2(1,4-bdc) 2(dabco) (dabco-1,4-diazabicyclo[2.2.2]octane), Ni 2(2,6-ndc) 2(dabco) (DUT-8, 2,6-ndc - 2,6- naphthalenedicarboxylate), Ni 2O 5(btb) 2 (DUT-9, btb - benzene-1,3,5-tribenzoate), Zn 4O(btb), and (Zn 4O(dmcpz) 3) (dmcpz - 3,5-dimethyl-4-carboxypyrazolato) at 298 K were investigated using volumetric methods. Up to 1 bar pressure (at 298 K), microporous MOF with open metal sites HKUST-1 shows the best performance in SF 6 adsorption and microporous Zn 4O(dmcpz) 3 in CF 4 adsorption. At high pressure, mesoporous MIL-101 and DUT-9 have the highest storage capacities for both gases among the MOFs investigated.
