The exploration of graphene-based electrochemical sensors has aroused intensive interest in applicationresearch. Here, we report the decoration of a reduced graphene oxide hydrogel film with Cu2O througha facile electrodeposition method and show that the as-prepared Cu2O/graphene hydrogel film can bedirectly utilized as an electrochemical H2O2 sensor. The morphology and structure of the hydrogelcomposite are characterized, and the optimal electrodeposition time is determined. The graphene/Cu2Ohydrogel film acting as a H2O2 sensor exhibits high electrochemical sensing properties in terms ofresponse, detection limit and selectivity. The present study could expand the potential of graphenehydrogel materials in the fields of sensors and biosensors.
