From Bifunctionality to Multifunctionality: Nitrogen-Doped Carbon Nanostructures (CN x ) for Electrocatalytic Applications in Fuel Cells and Beyond

High Resolution Image Download MS PowerPoint Slide This article provides an overview of the studies performed in our laboratories for developing nitrogen-doped carbon nanostructures (CN x ) as precious-metal-free bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) electrocatalysts for unitized regenerative fuel cells (URFCs). Additionally, our recent studies exploring the applications of these catalysts in halogen production via oxygen-depolarized cathode (ODC) technology have also been discussed. Future perspectives, challenges, and potential research avenues for exploring these materials as ‘multifunctional’ electrocatalysts have also been highlighted.
