a) Permeation properties for the CO2/CH4 mixture (1:1) separation at 298 K and Δp = 3 bar for MMMs comprising Matrimid® and NH2 MIL 53(Al) MOF crystals with different morphologies (nanoparticles (NP), nanorods (NR) and microneedles (MN)) as a function of the filler loading. Effect of the trans-membrane pressure different on the b) CO2 permeability and c) CO2/CH4 separation factor of the 16 wt% NH2-MIL-53(Al)@Matrimid® MMMs prepared with different filler morphologies. The data are average values of at least two membranes and error bars correspond to standard deviation. ▲ Nanorods, ● nanoparticles, ◊ microneedles and Matrimid®.
