biostudies-literatureUnknown17(38)Perez-Roman BThe oxygen reduction reaction (ORR) is critical to energy conversion technologies and requires efficient catalysts for superior performance. Herein, nitrogen-doped carbide-derived carbon (N-CDC) catalysts are prepared using novel engineered molecular architectures based on polymer-derived ceramic technology. The obtained catalyst materials show a surface N concentration of >5 wt % and a hierarchically porous structure, resulting in a specific surface area of over 2000 m² g^-1. Subsequently, the electrocatalytic activity toward the ORR is studied in different media (acid, neutral, and alkaline conditions) using a rotating ring-disk electrode. The N-CDC catalysts demonstrate clear improvements in performance due to nitrogen doping in neutral and acidic media, while textuACS applied materials & interfaces53388-53401https://www.ebi.ac.uk/biostudies/studies/S-EPMC12464907biostudies-literatureSynergistic Effect of Nitrogen Doping and Textural Design on Metal-Free Carbide-Derived Carbon Electrocatalysts for the ORR.PMC12464907Pascual LPerez-Roman BRubio-Marcos FMazo MALopez-Sanchez JRecio FJfalseSynergistic Effect of Nitrogen Doping and Textural Design on Metal-Free Carbide-Derived Carbon Electrocatalysts for the ORR.The oxygen reduction reaction (ORR) is critical to energy conversion technologies and requires efficient catalysts for superior performance.
