Abstract

The effect of purification condition of a chromium terephthalate MIL-101 on gas storage (H₂, CO₂, and C₂H₂) and C2 hydrocarbon separations was investigated for MIL-101a, MIL-101b, and MIL-101c, which were obtained by three-step sequential purification using hot water/ethanol and aqueous NH₄F solution treatments. MIL-101c was the best in terms of gas storage capacities among the three samples possibly due to the removal of free and coordinated terephthalic acids. Remarkably, MIL-101c exhibits among the highest total hydrogen uptake at 50 bar and 77 K (9.9 wt%) and shows considerably large deliverable capacity between 1.5 and 50 bar (7.6 wt%). Moreover, MIL-101c shows among the highest C₂H₂ storage capacity (6.4 mmol g^-1) and deliverable capacity (4.3 mmol g^-1) at 1 bar and 313 K. For C₂H₂/C ₂H₆, C₂H₂/C₂H ₄, and C₂H₄/C₂H₆ separations, MIL-101c exhibits higher adsorption capacities, working capacities and adsorption figure of merit (AFM) values while MIL-101b shows higher selectivities and sorbent selection parameters. These results clearly show that a proper purification of MIL-101 is important for gas storage and gas separations.
