Phase modulation of 1T/2H MoSe2 nanoflowers for highly efficient bifunctional electrocatalysis in rechargeable Li–O2 batteries

Nanoflower-like 1T/2H MoSe 2 nanosheets were prepared by a two-step hydrothermal method, which combines the advantages of 1T and 2H phase to deliver superior bifunctional electrocatalytic activities in Li–O 2 batteries.
