Electrochemical Sensing of Nitric Oxide on Electrochemically Reduced Graphene-Modified Electrode
Figure 4
The Nyquist plots of different electrode recorded in the presence of 5 mM (1 : 1) by applying an AC impedance with 5 mV amplitude in a frequency range from 0.1 Hz to 100 kHz under open-circuit potential conditions. (a) GO/GC electrode, (b) ERG/GC electrode, and (c) bare GC electrode.
