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

Figure 3

CVs of GNR/Co3O4/GCE were recorded in the absence (curve b) and presence of 30 μM H2O2 (curve a) in 0.1 M PBS (pH 7.4). CVs were also recorded using a bare GCE in 0.1 M PBS (pH 7.4) with 30 μM H2O2 (curve c). .
