Abstract:
Herein, graphene oxide is produced by electrochemical oxidation method from graphite rod to examine its hydrogen peroxide sensing ability. The electrochemically produced graphene oxide is characterized by SEM and XRD. A few layers of Graphene Oxide(GO) sheets and corrugations in graphene sheets appeared intensely crumpled and folded into a typical wrinkled structure after electrochemical oxidation. Electrochemical measurements are carried out cyclic voltammetry (CV) and chronoamperometry (CA) on graphene oxide and graphite. As a result, graphene oxide exhibits the highest performance toward electrochemical oxidation of H۲O۲ in ۰.۱ M phosphate buffered solution (PBS). In addition, CA is employed for the determination of H۲O۲ at the applied potential of ۰.۰ V (vs. Ag/AgCl). The electrochemical sensor exhibits fast and selective responses to H۲O۲ concentration.
