We report a widely applicable graphene edge functionalization method to increase oxygen reduction reaction electrocatalytic activity by chemically crafting diamino-benzene derivatives to ortho-quinone sites on holey graphene edges trough simple condensation reaction. The Zn-air batteries assembled by the resultant electrocatalyst outperform those constructed by Pt/C electrocatalyst. (C) 2018 Elsevier Ltd. All rights reserved.
