摘要：

Partially cracked carbon nanotubes (CCNTs) were obtained by KOH etching of multi-walled carbon nanotubes (MWNTs). Active edge sites were newly added and different pore distribution were simultaneously obtained. The prepared CCNTs exhibit almost 2 times higher discharge capacity in comparison to raw MWNTs, and present similar characteristics as graphene in O-2 chemisorption, which leads to higher oxygen reduction reactivity.
