N1s XPS and LSV measurements of NO2-NHCs which were deposited on Au films by EC deposition (a and b, respectively) and base-induced deprotonation (c and d, respectively). Measurements were performed prior (black-colored) and after (red-colored) one cycle of LSV. LSV conditions: 0.1 M HCl and scan rate of 0.1 V/s.
