Hydrogen Peroxide Electrocatalytic Oxidation Using a Shuttlelike Nano-CuO Modified Electrode

Uturu Imo

drothermal synthesis was used to make CuO nanocrystals. Scanning electron microscopy was used to examine the nanomorphology. CuO's to create nano-CuO/GCE modified electrode, the generated shuttlelike CuO nanocrystals were changed to Glass Carbon Electrode (GCE). In a 0.01 M NaOH containing 0.09 M KCl electrolytes, the improved electrode demonstrated good electrocatalytic properties towards hydrogen peroxide. The electrocatalytic response current of this sensor was proportional to the H2O2 concentration under ideal testing conditions.
