Figure 1. Electrochemical measurements of ZnCl2 electrolytes with and without SPr-Bpy. (A) CV profiles of 5 mM ZnCl2 with 0.25 mM SPr-Bpy (blue) at 25 mV s-1. The blank case without SPr-Bpy (grey) is presented for comparison. Inset: molecular structure of SPr-Bpy. (B) CV curves at various scan rates. Inset: linear fit of peak current vs. the square root of scan rate. (C and D) LSV results (C) and Tafel curves (D) in 0.5 M ZnCl2 with 25 mM SPr-Bpy (blue) and blank group (grey) at 10 mV s-1.
