文摘
- •
A composite with a 3D stacked-up nanostructure composed by Mn3O4, Co3O4 and graphene.
- •
The novel composite exhibits superior ORR activity to Co3O4/GO and Mn3O4/GO alone.
- •
The enhanced synergy in this composite is responsible for the ORR activity.
- •
There exists an interphase ligand effect between two spinel oxides and graphene.
