Fig. 6From: 2D-enabled membranes: materials and beyondSingle-gas permeability of various gases with different kinetic diameters across the 2-μm-thick MXene membrane at 25 °C and 1 bar. The inner graph showed the selectivity of 3 equimolar mixed gases [42]. Adapted with permission from ref [42]. Copyright 2018 for the John Wiley and SonsBack to article page
