Abstract

We report an efficient ORR electrocatalyst containing cobalt single atom and cobalt nanoparticle active sites embedded in a porous nitrogen-doped graphitic carbon network. The robust electrocatalyst exhibits superior electrochemical ORR activity with onset and half-wave potentials of 0.96 V and 0.87 V (vs. reversible hydrogen electrode), respectively, and has excellent durability and methanol tolerance further enhancing the potential of this system for practical applications. © 2024 The Royal Society of Chemistry.
