Optimizing Graphene Oxide Interlayer Spacing for Zeolitic Imidazolate Framework-8 Growth Toward Enhanced Shale Oil Separation. [PDF]

Adv Sci (Weinh)
Quaternary ammonium salts are used to control the spacing between GO layers, enabling in situ growth of ZIF‐8. The resulting ZIF‐8‐GO membrane exhibits nearly complete rejection of n‐docosane in n‐hexane, solvent permeance of 16.4 ± 0.8 L m−2 h−1 bar−1, and enriches alkanes and aromatics with a molecular weight cut‐off of 310 g mol−1 in shale oil ...
