Mechanochemical synthesis of graphene oxide for fabrication of 3D graphene-based hydrogel/aerogel

Past few decades, graphene oxide (GO) has attracted significant attention due to its excellent properties that can be utilized for various other applications such as electronic and energy storage devices, biosensors and optical materials. Nevertheless, large-scale production of high quality GO is still a challenging task for researchers and since industrial-scale chemical synthesis of GO are inherently generating large amount of toxic, it is more than necessary to find a cheaper and cleaner way of its production. However, recently mechanochemical reactions offers advantages over traditional solvent based chemistry reflected in better yields and selectivity, better energy- and atom-economy and reduced waste generation. Herein, we report versatile and eco-friendly approach to prepare GO by use of mechanochemical ball milling and fabrication of 3D graphene-based mesoporous frameworks via easy and eco-friendly hydrothermal process using as synthesized GO. Graphene hydrogels are a new class of 3D carbon monoliths holding promise for applications as diverse as electrochemical energy storage, CO2 capture, tissue engineering and pollutant adsorption. They consist of entangled layers of graphene, albeit they partially retain the excellent properties of monolayer graphene.
