A facile simple strategy is employed to in-situ fabricate Fe/Fe3C decorated 3-D porous nitrogen-doped graphene.
MIL-100(Fe), a kind of metal-organic framework, is proved playing a structure-directing role in this advanced synthesis route.
This material possesses excellent bi-functional electro-catalytic activity for ORR and OER and shows good electrochemical performance while used as cathode material for Li–O2 batteries.
The MOF-assisted synthesis method would be a promising new strategy for the synthesis of 3-D porous graphene materials.
