- 요약Metalated nitrogen-doped carbon (M-N-C) materials are an important class of catalysts that feature isolated metal ions dispersed within a conductive nitrogen-doped graphitic support. Fe-N-C variants of these materials have gained prominence as electrocatalysts for the oxygen reduction reaction (ORR) in fuel cells. The catalytic active sites consist of single-atom Fe ions coordinated by nitrogen atoms within the graphitic material (FeNx), resembling Fe-porphyrins (i.e., x = 4) and related Fe-macrocycles commonly encountered in molecular and biological catalysts. The same class of M-N-C materials have been identified as effective catalysts for aerobic oxidation of organic molecules. The latter reactions are conceptually similar to the electrochemical ORR, using protons and electrons from chemical bonds in the organic molecules to reduce O2 to water, but their mechanisms have received much less attention. The present study of aerobic oxidation reactions with an array of different Fe-N-C catalysts reveals that catalytic activity does not depend on the FeNx site density but, instead, the basicity of nitrogen atoms within the catalyst. This conclusion is supported by kinetic and spectroscopic data and observation of similar behavior across three different liquid-phase aerobic oxidation reactions.
