Fast-scan cyclic voltammetry of H₂O₂. a The applied potential was scanned at 400 V s⁻¹. b Background current at the carbon surface produced by the rapid scan (solid line). c Background-subtracted cyclic voltammogram of 100 μM H₂O₂ at pH 7.4. d Color plot containing 200 background-subtracted cyclic voltammograms recorded over 20 s.
