Abstract
Adjusting the hydrogen-binding free energy (?GH*) of two dimensional (2D) MoS2 by changing the interlayer distance has been an effective strategy to improve the intrinsic activity for hydrogen evolution reaction (HER). Herein, a facile solvothermal access via various ratio of N, N-dimethylformamide (DMF)/H2O has been used to modulate interlayer distance of nanostructured MoS2. With increasing of DMF, the interlayer distance of MoS2 can be expanded to 9.4
