a CVs on the GC disk electrode in 1 mM redox species containing solutions at the scan rate of 10 mV s−1 without stirring. b CVs on the GC disk electrode in 1 mM TEMPO-containing solution at various scan rates without stirring. c The plots of anodic peak current density versus the square root of the scan rate. WE: GC disk; CE: Pt wire; RE: Ag/Ag+ reference electrode; Electrolyte: ACN containing 100 mM TBAPF6 and 1 mM of redox species. d Linear sweep voltammetry (LSV) on the Pt plate (solid line) and GC plate (dashed line) electrodes in ACN containing 20 mM ferrocene, 80 mM TEMPO, 80 mM TEMPOL, or 20 mM thianthrene and 100 mM TBAPF6 with stirring at 700 rpm. CE: Pt wire; RE: Ag/Ag+ reference electrode. Source data are provided as a Source Data file.
