文摘

Coordinatively unsaturated metal–organic frameworks (MOFs) were studied for boron trifluoride (BF₃) sorption. MOF-74-Mg, MOF-74-Mn, and MOF-74-Co show high initial uptake (below 6.7 × 10^–3 bar) with negligible deliverable capacity. The BF₃ isotherm of MOF-74-Cu exhibits gradual uptake up to 0.9 bar and has a deliverable gravimetric capacity that is more than 100% higher than activated carbon. Two other Cu²⁺ MOFs, MOF-505 and HKUST-1, have slightly lower deliverable capacities compared to MOF-74-Cu.
