Abstract
3D mesoporous Cu,Co-N-C nanosheet architectures are fabricated, showing greatly enhanced catalytic activity and stability in the ORR relative to their mono-metallic counterparts. Such superiority results from the synergistic interplay of their bimetallic sites, which can offer more accessible active sites and efficiently modulate their surface/interface electronic structures.
