Nitrogen-Doped Carbon Activated in Situ by Embedded Nickel through the Mott-Schottky Effect for the Oxygen Reduction Reaction.
TL;DR: In situ activation of a uniquely structured nitrogen-doped carbon/Ni composite catalyst for the ORR is demonstrated and it is suggested that the donated electrons are transferred to pyridinic N primarily, which ought to enhance the catalytic activity intrinsically.
