a A cartoon illustrating the gas separation through porous Zn2(Bim)3 nanosheets. Only Zn atoms are shown for clarity, and the light blue planes represent the nanosheets regardless of their amphiprotic natures. The blue line indicates the pathway of H2 and the red line represents the pathway of CO2 [27]. b The change of permeance of H2/CO2 and mixture separation factor of Zn2(Bim)3 nanosheet membrane for different temperature condition [27].
