Schematic Illustration of In Situ Crystallization of ZIF-8@rGO for the Naturally Dried Aerogel

Zn2+/reduced graphene oxide hydrogel (rGH) was prepared first by hydrothermal synthesis, followed by the in situ crystallization of ZIF-8@rGH by dipping in dimethyl imidazole (2-MIM) and natural drying of the hydrogel after a pre-freeze.
