Electrochemical sensing behaviour of Ni doped Fe3O4nanoparticles

Ni doped Fe 3 O 4 nanoparticles were synthesized by simple hydrothermal method. The prepared nanomaterials were characterized by X-ray diffraction analysis, DRS-UV-Visible spectroscopy and field emission scanning electron microscopy. The XRD confirms the phase purity of the synthesized Ni doped Fe 3 O 4 nanoparticles. The optical property of Ni doped Fe 3 O 4 nanoparticles were studied by DRS UV-Visible analysis. The electrochemical sensing property of pure and Ni doped Fe 3 O 4 nanoparticles were examined using uric acid as an analyte. The obtained results indicated that the Ni doped Fe 3 O 4 nanoparticles exhibited higher electrocatalytic activity towards uric acid.
