The cyclic voltammetric(CV) behavior of silver oxide electrodes were investigated as function of scan rate and mass ratio of common Ag₂O(d=0.5 μm) and nano Ag₂O. The peak shapes in CV diagramms were differed for the three electrodes when the scan rate was 0.5 mV/s and their peak current values were obviously different at any scan rate. The optimum mixture electrode(sample A) exhibited remarkable cyclic reversibility, while the pure nanophase Ag₂O electrode(sample F) was wear in receiving charges. The common Ag₂O electrode(sample C) was just in between them. The best electrochemical property of the optimum mixture electrode could be due to the effectively reasonable distribution of the electroactive substances on the surface of electrode.
