- Abstract
Abstract: Pyridinic nitrogen species on nitrogen‐doped carbon catalysts were recently found to create active sites for the oxygen reduction reaction (ORR). Bottom‐up assembly of pyridinic‐nitrogen‐containing aromatic molecules on graphitic carbon electrodes is a promising synthesis method to design ORR carbon catalysts with a high density of active sites. Herein, we report the preparation of a model catalyst by dropping a solution of dibenz[<italic>a</italic>,<italic>c</italic>]acridine (DA) molecules onto a highly oriented pyrolytic graphite (HOPG) surface. The DA molecules form a two‐dimensional ordered structure along the direction of the HOPG substrate by self‐organization. Adsorbed DA on the HOPG surface shows high ORR activity in terms of specific activity per pyridinic nitrogen and is comparable to that of pyridinic‐nitrogen‐doped carbon catalysts.
