abstract
The complexity in composition and structures of Metal-Organic frameworks (MOF) is continually increasing, and novel applications are continuously being explored. Yang and Li revealed, through low-pressure N 2 and O 2 adsorption measurements at 298 K, that O 2 is adsorbed preferentially over N 2 in MOF-177 with an evaluated selectivity of about 1.8 at 1 atm and 298 K. Hupp and co-workers studied the kinetic separation of propene and propane in another series of isostructural MOFs. Krungleviciute and co-workers tested the kinetic and equilibrium adsorption of CF 4 and Ar on Co 3(bpdc)3(bipy) and HKUST-1. Lang and co-workers reported the adsorptive separation of a solid mixture of naphthalene and anthracene by Ni 2(2-OH 2)(1,3-bdc)2(tpcb). De Vos and co-workers have shown that MIL-47 and MIL-53 are capable of separating EB and St in the liquid phase.
