“…The symmetry of the electrode reaction was investigated by calculating the charge transfer coefficient ( α ) using the slope (
) of
curve
(R 2 : 0.981)), and α was determined as 0.697 (Figure S4). This indicates an asymmetric behavior of the transition state regarding the applied potential, acting akin to a product‐like transition state
[26, 38, 39]. The proton: electron ratio belonging to the nicotine oxidation was specified from the slope of
curve, and a −64.0 mV per pH signifies the ratio of 1 (Figure S5).…”
