文摘
- •
Novel vertically self-standing Ni@Co3O4 web-like nanofiber arrays were synthesized.
- •
They show high bifunctional activity for oxygen reduction and evolution reactions.
- •
A rare high specific capacity of 17118 mAh g−1 was demonstrated.
- •
128 stable cycles was achieved with the capacity limited to 500 mAh g−1.
