A facile, fast, and convenient route was suggested for the fabrication of Prussian blue nano particles
(PBNPs) assembled on reduced graphene oxide (RGO) modified glassy carbon electrode (PBNPs|RGO|
GCE). RGO was electrodeposited on the surface of GCE and the prepared RGO|GCE was immersed into a
ferric-hexacyanoferrate(III) solution and PBNPs were assembled on the RGO|GCE for a certain period of
time. The PBNPs film thickness can be easily controlled by adjusting the assembling duration. The developed
PBNPs|RGO|GCE was successfully used for determining hydrogen peroxide, with a linear response
over the concentration range 0.5-400 μM, a good accuracy and precision, detection limit 0.44 μM, and
sensitivity 1168 mAM-1 cm-2.
