Abstract

© 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim In this work a facile synthetic process for modified carbon nanotubes for ORR catalysis is described. X-ray photoemission spectroscopy (XPS) and Raman spectroscopy confirm the inclusion of surface carbonyl groups in these modified nanotubes. Via rotating disk electrode (RDE) experiments in an alkaline medium, the modified nanotubes were found to equal the activity of a Pt/C standard and exceed the stability of the platinum catalyst. Density functional theory (DFT) and scanning tunneling microscopy (STM) studies serve to provide theoretical and experimental electronic property information which explain the improved ORR activity seen by the modified nanotubes.
