英文摘要	Mesocrystal hexagonal Co3O4 nanosheets with highly exposed {111} crystallographic planes were successfully synthesized by the conversion of hexagonal Co(OH)(2) nanosheets. They demonstrate uniform size with length of 400 nm. When applied as anode material for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs), they delivered high specific capacity of 1000 mAh g(-1)@0.1 C and 640 mAh g(-1)@2 C, 600 mAh g(-1)@0.1 C and 350 mAh g(-1)@2 C, respectively. These excellent electrochemical properties attribute to the ordered ions diffusion pathway originated from the mesocrystal nanostructure. With these outstanding performances, the mesocrystal hexagonal Co3O4 nanosheets enable provide meaningful anode materials for LIBs and SIBs. (C) 2017 Elsevier B.V. All rights reserved.
