Developing low-cost and highly efficient oxygen reduction reaction (ORR) catalysts with excellent methanol tolerance is crucial for the commercialization of direct methanol fuel cells (DMFCs). In this work, we construct single Fe atoms anchored on N,S-codoped graphene (Fe1/NSG), where the S atom in...
