WebJan 22, 2016 · Since the pyri-HOPG sample is nearly free of graphitic N, the ORR results indicate that pyridinic N rather than graphitic N reduces the ORR overpotential and creates the active site. The activity of the grap-HOPG sample could also be ascribed to the presence of pyridinic N as a minor component (0.04 at. %).
