Soft-Chemical Tuning of Structural, Defect, and Morphological Properties of MoS 2 : Elucidating the Governing Factors of Electrocatalytic Activity

Two-dimensional transition-metal dichalcogenide nanosheets made of MoS2 are widely studied owing to their applications as electrocatalysts and electrode materials. To specify key design parameters for optimizing catalytic performance of MoS2, we developed a soft-chemical lattice manipulation strategy to precisely tune their structural, defect, and morphological characteristics via self-assembly of the exfoliated MoS2 nanosheet with various guest cations.
