Hematite (alpha-Fe2O3) nanoparticles were synthesized by the solid transformation of ferrous hydroxide and ferrihydrite in hydrothermal condition. The as-prepared alpha-Fe2O3 nanoparticles were characterized by UV-vis, PL, XRD, Raman, TEM, AFM, FESEM, and EDX analysis. The experimental results indicated the formation of uniform hematite nanoparticles with an average size of 45 nm and perfect crystallinity. The electrochemical behavior of a GC/alpha-Fe2O3 electrode was studied using CV and EIS techniques with an electrochemical probe, [Fe(CN)(6)](3-/4-) redox couple. The electrocatalytic activity was investigated toward DA oxidation in a phosphate buffer solution (pH 6.8) by varying different experimental parameters. The chronoamperometric study showed a linear response in the range of 0-2 mu M with LoD of 1.6 mu M for DA. Square wave voltammetry showed a linear response in the range of 0-35 mu M with LoD of 236 nM for DA.
