Abstract

In this work, a non-precious metal catalyst consisting of Co ₉S₈ nanoparticles surrounded with nitrogen-doped graphene-like carbon (Co₉S₈-N-C) was developed for oxygen reduction in alkaline media. Improved activity has been measured with the Co₉S₈-N-C catalyst relative to Pt/C and a non-precious metal catalyst based on Fe instead of Co (Fe-N-C). An extensive physical characterization, including XRD, SEM, TEM, and XPS and electrochemical kinetic analysis was conducted to provide insight into the catalyst morphology and structure.
