Abstract

A facile and green method for the synthesis of graphene oxide sheets (GOs)-prussian blue nanocomposites has been presented via a spontaneous redox reaction in a aqueous solution containing FeCl3, K3[Fe(CN)6] and graphene oxide sheets. Electrochemical property investigation demonstrates PB nanocubes formed on the surface of GOs retain their excellent electrochemical activity and the GOs can enhance the electron transfer between PB and GC electrode. Moreover, the obtained nanocomposites even have shown a higher sensitivity toward the electrocatalytical reduction of H2O2 than that of multiwalled carbon nanotube/PB nanocomposites. Given their extraordinary electrochemical properties and the green preparation, as-prepared GO-PB nanocomposites have great potential in the field of electrochemical sensor and biofuel cell.
