A Hydrogen Peroxide Electrochemical Sensor Based on Co-Doped Fe3O4 Nanoparticles
In the present paper, the Co-doped Fe3O4 nanoparticles have been successfully synthesized by the co-precipitation process. The morphologies size of the Co-doped Fe3O4 nanoparticles were characterized using scanning electron microscopy (SEM). The structure of the products were characterized by Xray diffraction (XRD). The composition of the product was analyzed by energy dispersive X-ray detector (EDS). The results show that the phase structure of the Co-doped Fe3O4 nanoparticles is spinel Fe3O4 with the particle size ranging from 40 to 50 nm. The prepared Co-doped Fe3O4 nanoparticles electrode was then applied to detect hydrogen peroxide (H2O2) in 0.01 M pH 7.0 phosphate buffer medium.
