Abstract
A one-pot approach for the scalable production of novel interconnected reduced graphene oxide (IC-RGO) is demonstrated). The method consists of two steps: oxidation of graphite into graphene oxide (GO); and concomitant reduction and interconnection of GO. IC-RGO is formed without additional chemical and reduction agents. Instead, interconnection of graphene oxide is enabled thorough inherently presenting oxygen functional groups produced during the first step of synthesis.
Claims11
A method of producing an interconnected, reduced graphene oxide comprising:
- (a) oxidizing a quantity of graphite for about 10 to 20 hours with an acid mixture comprising manganese, thereby producing a layer structured graphene oxide;
- and
- (b) removing functional groups from the graphene oxide by heating the layer structure graphene oxide to 100-120° C. for 5-20 minutes to form reduced graphene oxide, said reduced graphene oxide simultaneously forming covalent linkages, thereby forming three dimension, interconnected, reduced graphene oxide sheets.
