Mild annealing enables inactive nitrogen (N)‐doped amorphous carbon (a‐C) films abundant with chaotic bonds prepared by magnetron sputtering to become effective for the oxygen reduction reaction (ORR) by virtue of generating pyridinic N. The rhythmic variation of ORR activity elaborates well on the subtle evolution of the amorphous C−N bonds conferred by spectroscopic analysis.
