Abstract:

We have synthesized Fe3O4 nanoparticles by simple hydrothermal method. The synthesized material was characterized by XRD, FT-IR and FE-SEM etc., The FT-IR spectrum confirms the formation of Fe3O4. XRD confirms the structure and phase purity of the Fe3O4 nanoparticles. The morphological property was characterized by FE-SEM. The synthesized Fe3O4 nanoparticles were used to modify the glassy carbon electrode (GCE) and the modified electrode (n-Fe3O4/GCE) was found to exhibit electrocatalytic activity for the oxidation of uric acid (UA). It shows that the Fe3O4 nanopowder exhibits promising applications in the development of bio-sensors.
