▎ 摘　　要

A three-dimensional (3D) N-doped graphene aerogel with porous structures and uniformly distributed PtRu NPs (N-GA/PtRu) is constructed by a simple, rapid and eco-friendly method. The N-GA/PtRu exhibits an unprecedented performance towards the methanol electrochemical oxidation reaction. Notably, N-GA/PtRu can be directly used as the anode of direct methanol fuel cells by simple physical pressing without the need for any binders or additives.
