Abstract
In this paper, an electrochemical nonenzymatic sensor using three dimensional Fe3O4 accumulated sphere-like nanocomposites as the carriers was designed. The decorated materials with homogeneous stacked sphere-like morphologies were synthesized through a facile one-step solvothermal reaction by selecting Fe(CO)5 as the iron sources and absolute ethanol as the solvent. We used cyclic voltammetric (CVs) and current-time (I-t) curves to detect the current response towards H2O2. Achieved consequences demonstrated that the as-prepared nonenzymatic H2O2 sensor revealed the low detection potential (â0.1â¯V) as well as high sensitivity (205â¯Î¼Aâ¯mMâ1â¯cmâ2), wide linear range (5.0â¯Î¼M-4.995â¯mM) and low detection limit (2â¯Î¼M, S/Nâ¯=â¯3). In addition, the novel nonenzymatic sensor was successfully applied to the detection of H2O2 in pasteurized milk samples.
