electrochemical production of graphene oxide and its application as a novel hydrogen peroxide sensor

Hydrogen peroxide sensing ability. the electrochemically produced graphene oxide is characterized by sem. 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 h2o2 in 0.1 m phosphate buffered solution (pbs). in addition, ca is employed for the determination of h2o2 at the applied potential of 0.0 v (vs. ag/agcl). the electrochemical sensor exhibits fast and selective responses to h2o2 concentration.
