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.

Interconnected reduced graphene oxide

Doping and functionalization could significantly assist in the improvement of the electrochemical properties of graphene derivatives. Herein, we report a one-pot synthesis of fluorinated graphene oxide (FGO) from graphite. The surface morphology, functionalities and composition of the resulting FGO have been studied using various surface characterization techniques, revealing that layer-structured nanosheets with &#x2dc;1.0 at. % F were formed. The carbon bound F exhibited semi-ionic bonding characteristic and significantly increased the capacitance of FGO compared to graphene oxide (GO). Further, the FGO has been employed for the simultaneous detection of heavy metal ions Cd, Pb, Cuand Hgusing square wave anodic stripping voltammetry; and a substantial improvement in the electrochemical sensing performance is achieved in comparison with GO.
