Using equation 5 (n=4 for ethanol, n=2 for isopropanol, n'=1), we determined a mean kc value of 4.2 ± 0.4 M -1 s -1 and 0.243 ± 0.009 M -1 s -1 for ethanol and isopropanol, respectively (N=5). These values are reasonable in comparison to prior literature for TEMPO catalyzed alcohol electro-oxidation. We note the increased relative error observed for ethanol is likely caused by small Csub values (Figure ), which require dispensing low ethanol volumes (sub 200 µL), approaching the limits of the solution handling hardware's precision. Each autonomous campaign consisted of 30 CVs each (15 in the presence of substrate to determine ipl, and 15 in its absence to determine ip) and took around 3-4 hours, depending on the chosen parameters. In between each measurement the solution was removed from the cell, flushed with water, primed with measurement solution, rinsed, and refilled. We estimate such cumbersome cleaning and dispensing regime would involve 300 unique solution dispensing and mixing operations, thus taking several experimental sessions to complete. Based on our experience, we further posit it would be more prone to dispensing and other human errors.
