(A) Chronoamperograms obtained at NiO–Pt–H/B,1,10,P,1,10,PDNiPF6/CPE (a) in the absence, (b) in the presence of 50.0 µM and (c) in the presence of 100.0 cysteamine at pH 7.0. (B) Cottrell’s plot for cysteamine oxidation data on the surface of NiO–Pt–H/B,1,10,P,1,10,PDNiPF6/CPE. (C) Dependence of Ic/IL on the t1/2 derived from the chronoamperogram data. (D) The charge–time curves derived from the chronoamperogram data.
