Synergistically promoting proton-coupled electron transfer of oxygen reduction with dual atomic sites on high-curvature carbon onions for highly efficient Zn–air batteries
Key Points
Higher efficiency achieved with dual atomic sites, facilitating improved proton-coupled electron transfer.
Key evidence shows significant promotion of oxygen reduction by adjacent Cr and Fe atoms.
Experimental investigation highlights the role of carbon onions in enhancing battery performance.
This work supports future development of efficient Zn–air batteries with advanced carbon materials.
Abstract
Adjacent Cr atoms promote water dissociation and collaborate with Fe atoms in intermediate conversion during the ORR.
