a Cyclic voltammetry (CV) curve of 2-PAP in the [Emim][BF4] electrolyte with glassy carbon (GC) as the electrode. b The peak potentials of two reduction peaks in eight different ILs. The reaction processes corresponding to the two peaks are illustrated. c The peak currents of the two reduction peaks for 2-PAP in the [Emim][BF4] electrolyte are shown for different MG ribbons. Reaction conditions: H-cell, ILs-MeCN (1:1, v/v), 5 mM 2-PAP, scan rate of 0.05 V s⁻¹, a three-electrode system with (a, b) a glassy carbon (GC) electrode or (c) MG ribbons as the working electrode, a Pt wire counter electrode, and an Ag/AgCl reference electrode. The potential values are not iR-corrected. Source data for Fig. 3 are provided as a Source Data file.
