Prussian Blue Modified Solid Carbon Nanorod Whisker Paste Composite Electrodes: Evaluation towards the Electroanalytical Sensing of H₂O₂

Figure 4

Reduction process of H₂O₂ on SCNR paste electrodes containing 0% (w/w) PB (solid line), 10% (w/w) PB (dashed line), and 20% (w/w) PB (dotted line). 10.0 mM H₂O₂ in 0.1 M phosphate buffer, pH = 7.0. Scan rate 25 mV/s for SCNR paste electrode containing no PB and v = 50 mV/s for SCNR paste containing 10 and 20% (w/w) PB.
