Nanosheet-like manganese ferrite grown on reduced graphene oxide for non-enzymatic electrochemical sensing of hydrogen peroxide

In-situ formation of manganese ferrite (MnFe2O4) nanosheets anchored reduced graphene oxide (rGO) was synthesized through one-pot hydrothermal method. The rGO/MnFe2O4 nanocomposite modified glassy carbon electrode was used for the electrochemical reduction and detection of hydrogen peroxide (H2O2). The nanocomposite modified electrode showed the highest catalytic current response for H2O2 reduction and the detection limit was estimated to be 50 nM using differential pulse voltammetry. Moreover, the modified electrode showed good stability, reproducibility and selectivity in the presence of many interferents.232
