Abstract

Abstract : On page 6845, Q. Zhang, M.‐M. Titirici, F. Wei, and co‐workers describe a bifunctional graphene catalyst with abundant topological defects through the facile carbonization of natural gelatinized sticky rice and probe the underlying oxygen electrocatalytic mechanism. A nitrogen‐free configuration with adjacent pentagon and heptagon carbon rings is revealed to exhibit the lowest overpotential for both oxygen reduction and evolution catalysis.
