Figure 4

(a) Single gas permeation of the 40-nm membrane (blue line in insert figure indicates the Knudsen diffusion selectivity of H2 over other gases). (b) A 10,000 min continuous test of the 40-nm membrane for the separation of equimolar H2/CO2 mixture at room temperature. (c) A snapshot of MD simulation for the separation of equimolar H2/CO2 mixture through a bilayered MAMS-1 membrane (after 80 ns of simulation). (d) Gas permeance and H2/CO2 separation factors of the 40-nm membrane under seven heating/cooling cycles. Different colours represent various temperatures: blue, 20 °C; magenta, 40 °C; olive, 60 °C; orange, 80 °C; red, 100 °C and black, 120 °C.
