The nanorods were obtained by a hydrothermal method and characterized by scanning electron microscopy and X-ray diffraction. Cyclic voltammetry was used to evaluate the electrochemical performance of the modified GCE. The sensor exhibits excellent catalytic activity toward the oxidation of H2O2 and displays a rather wide linear range (from 2.5μM to 42.9mM), high sensitivity (21.74μA·mM−1), a low detection limit (2.45μM at an S/N of 3), and a response time of <5s. Fig. a A simple hydrothermal method was developed to prepare mono-dispersed single-crystal β-MnO2 nanorods, which was tested successfully for the electrocatalytic determination of H2O2 in aqueous solution. The resulting sensor exhibited wide linear range, high sensitivity, fast response, low detection limit and strong anti-interference ability.
