Abstract:
A novel one step solvo-thermal method was used to synthesize Iron oxide (Fe3O4) nanoparticles on
Nitrogen doped reduced graphene oxide (NrGO) as electrocatalyst for lead detection. The as-synthesized
nanocomposite was successfully characterized by X-ray diffraction technique to confirm the formation of
iron oxide nanoparticles on NrGO surface. Transmission electron microscopy confirmed the particle size
and particle distribution of Fe3O4 nanoparticles on NrGO surface. Fourier transform Infrared Spectroscopy
confirmed the nitrogen doping of Graphene oxide. Electrochemical properties of Fe3O4@NrGO composite
was investigated by Differential pulse voltametry, Cyclic Voltametry and electrochemical impedance
spectroscopy. The Lead(II) detection results of Fe3O4@NrGO nanocomposite was compared with that of
Fe3O4 nanoparticles and reduced graphene oxide. It is found that detection range of Fe3O4@NrGO
nanocomposite range was better than Fe3O4 nanoparticles and reduced graphene oxide.
