Abstract

<p>N-doped carbon materials have been attention which shows oxygen reduction reaction (ORR) activity. We clarified Pyridinic-N (nitrogen atom bound to C atoms) forms an active site for ORR. An ORR mechanism on N-doped carbon has been not clarified by experimental method. Recently, we also demonstrated dibenz[a,c]acridine, Pyridinic-N containing molecules, periodically adsorbed on HOPG (DA/HOPG) shows comparable ORR activities with that for Pyridinic-N-doped carbon. Herein, we investigated the state near nitrogen about DA/HOPG as model catalyst after the immersion into acid condition and after applying to voltage in acid condition by X-ray photoelectron spectroscopy measurement and infrared absorption spectroscopy measurement.</p>
