Chemically exfoliated 1T MoS₂ electrodes. a,b) Photographs of electrodes consisting of a thick film of chemically exfoliated 1T MoS₂ prepared by vacuum filtration and transferred onto rigid glass (a) and a flexible polyimide substrate (b). c) Side view of the electrode observed by scanning electron microscopy (SEM) showing the layered nature of the film made by restacking exfoliated MoS₂ nanosheets. d) High‐magnification image of restacked MoS₂ nanosheets. e) SEM image of as‐exfoliated monolayer 1T phase MoS₂ nanosheets. f) High‐angle annular dark‐field scanning transmission electron microscope image of monolayer 1T phase MoS₂. Inset: Atomic structure of 1T phase MoS₂ (Mo and S atoms are displayed in blue and yellow, respectively). g) XRD of bulk MoS₂ compared with as‐exfoliated restacked MoS₂. h) High‐resolution X‐ray photoelectron spectrum from the Mo 3d region of as‐exfoliated 1T MoS₂ (black). Contributions from 1T and 2H phase components in the Mo 3d spectrum are indicated by blue and red curves, respectively. Reproduced with permission.260 Copyright 2015, Nature Publishing Group.
