Abstract The oxygen reduction reaction (ORR) is a crucial process in electrochemical energy technologies, featuring fuel cells and metal‐air batteries the coming carbon‐neutral society. Carbon materials have garnered significant attention as economical, sustainable alternatives to precious metal catalysts. In particular, there been increasing reports recently that pentagons introduced into graphitic carbons promote catalytic activity for ORR. addition, interesting studies are reported on carbon materials’ synthesis, characterization, spin polarization properties with pentagonal defects. This review comprehensively summarizes formation mechanism, spin, (O 2 ) adsorption, ORR of catalysts By connecting dots between theoretical insights experimental results, this elucidates fundamental principles governing pentagon‐related offers perspectives future directions designing efficient based materials.

However, offer possibilities beyond these, which long-range order, topology, crystallographic nets, dimensionality extended structures. Indeed, range zero-dimensional cages one-dimensional chains or tubular networks, two- three-dimensional networks.
