Abstract:
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 ˜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 2+ , Pb 2+ , Cu 2+  and Hg 2+  using square wave anodic stripping voltammetry; and a substantial improvement in the electrochemical sensing performance is achieved in comparison with GO.

Claim (Index 1):
A method for synthesis of about 0.5 to about 1.5 at. % fluorinated graphene oxide comprising:\n mixing about n grams of graphite with about 5*n to about 40*n ml HF in a solution of about 50*n to about 150*n ml of H 2 SO 4 /H 3 PO 4  (10-x:x, where x=0.1 to 4) with stirring at a temperature of about 30 to about 80\u00b0 C. for a first period of time; adding about 3*n to about 10*n g KMnO 4  to the mixture and stirring the mixture at a temperature of about 40 to about 80\u00b0 C. for a second period of time; adding the reacted mixture to a container containing about 50*n to about 250*n ml of ice and about 1*n to about 10*n ml of H 2 O 2 ; separating solid comprising about 0.5 to about 1.5 at. % fluorinated graphene oxide from the mixture; rinsing the fluorinated graphene oxide; and drying the fluorinated graphene oxide.
