Die Aufklärung der katalytischen Zentren für die Sauerstoffreduktion (ORR) unterstützt die Entwicklung hocheffektiver Nichtedelmetallkatalysatoren. H.‐W. Liang, X. Feng et al. führen in ihrem Forschungsartikel auf S. 1644 eine NH4Cl‐Behandlung bei niedriger Temperatur durch, die verkapselte Metallnanopartikel wirksam aus dotierten Kohlenstoffen entfernt. Die derart verbesserte ORR‐Leistung bestätigt...
The development of metal‐N‐C materials as efficient non‐precious metal (NPM) catalysts for catalysing the oxygen reduction reaction (ORR) as alternatives to platinum is important for the practical use of proton exchange membrane fuel cells (PEMFCs). However, metal‐N‐C materials have high structural heterogeneity. As a result of their high‐temperature synthesis they often consist of metal‐Nx sites...
