Description:
Graphene oxide (GO) has shown great application prospects in many fields. Electrochemical oxidation is considered as a green, safe and efficient method to synthesize GO. This method usually requires an electrode composed of graphite with certain forms, and graphite particles may escape from the electrode, leading to a low yield of the product. In this study, we report a strategy for the synthesis of GO by electrochemical oxidation with a container having holes as anode region, in which was filled with exfoliated graphite at room temperature (RTEG). The use of the container fixes the worm-like RTEG in the electrochemical anode region, thus achieving a high yield and low-cost preparation of graphene oxide. Moreover, the HI-reduced EGO (rEGO) films have a high electrical conductivity, thus it can be used as the substrate of the non-enzymatic glucose biosensor. It is promising for EGO to be used in widespread field
