Kurzbeschreibung (Abstract)
Me[BOND]N[BOND]C catalysts are today's most prominent nanocarbon-based nonprecious-metal catalysts for the oxygen reduction reaction (ORR). Usually, these catalysts reveal a heterogeneous composition as at least one heat treatment step is involved in their preparation. As a consequence, it is difficult to correlate structural parameters with their activity to reduce oxygen or their long-term stability in proton-exchange-membrane fuel cell (PEM-FC). This contribution introduces the spectroscopic techniques that are most important to step forward in the development of these nonprecious-metal catalysts. Each technique is shortly introduced and its application is illustrated by selected examples of Me[BOND]N[BOND]C catalyst characterization. While today most of the techniques are applied ex situ, the characterization of catalysts under operating conditions (in operando or in situ) will become more and more important.
