Electrochemical Detection of H₂O₂ on Graphene Nanoribbons/Cobalt Oxide Nanorods-Modified Electrode

Figure 5

(a) CVs of GNR/Co₃O₄/GCE were recorded in 0.1 M PBS (pH 7.4) at a scan rate of 50 mV/s with successive additions of 10 μM of H₂O₂ in the range from 10 to 200 μM. (b) A linear calibration plot was made between vs. [H₂O₂].
