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

Figure 6

(a) A linear plot was made between the pH vs. redox potential of GNR/Co3O4/GCE. CVs were recorded in different pH (1, 5, 7.4, and 9) buffer solutions using a GNR/Co3O4/GCE. (b) Bar diagram shows the variations in the obtained current response (%) of 10 μM H2O2 after additions of 10 μM of AA, UA, glucose, PA, L-alanine, lactose, and L-tyrosine.
