Where n is the number of electrons transferred from the catalyst to the substrate (we assume n = 2 for all cases), n' is the number of electrons transferred between the catalyst and electrode in the absence of substrate (n'= 1), R is the gas constant, T is the temperature, F is Faraday's constant, and v is the scan rate. We chose to measure the rate of isopropanol electrooxidation to ensure the calculated rate constants were reasonable, as our group has previously measured the turnover frequency (TOF) of this system to be 0.51 s -1 at pH 10, which was validated using simulations. Figure shows CVs performed at 50 mV/s in pH 10 solution that were used to calculate a kobs value of 0.59 s -1 . Since our iplateau value was calculated almost 500 mV more positive than the E1/2 of our TEMPO catalyst, we can assume that the TOF of the system is equal to our kobs. Thus, the TOF for electrooxidation of isopropanol measured with our platform matches well with what has been previously reported.
