The carbon nanotubes (CNTs) are controllably drilled by supporting cobalt oxide.
- class="label">•
The drilled CNTs are used as cathodic catalyst for oxygen reduction reaction (ORR).
- class="label">•
Defects or edge carbons improve electron transfer and ORR activity.
- class="label">•
The combined effect of defects and electron transfer resistance on ORR is revealed.
- class="label">•
The suitably drilled CNTs show dramatically enhanced ORR performance.
