Molybdenum disulfide is regarded as the inheritor of Pt-based catalysts for the hydrogen evolution reaction (HER), arising from low-cost and abundant resource. However, the electrocatalytic efficiency of MoS2 is much lower than that of Pt-based catalysts, as a result of lacking edge active sites, poor activity of basal plane, and deficient conductivity. Herein, by introducing nanoflower-like MoS2 with PVP coating (PVP@MoS2) as catalyst, high performance for HER is observed. The higher efficiency of PVP@MoS2 is mainly due to the four points: (1) the formation of more spatial manipulated nanoflower structure by thin MoS2 slices exposing large amount of edge active sites; (2) improving basal plane atom utilization with the enlarged (002) plane from 6.2 to 6.8 Å; (3) the intrinsic conductivity of MoS2 increases, because the electron can transfer from C=O and C–N to MoS2; (4) the decreased hydrogen atom absorption energy from 0.815 to 0.684 eV extracts from DFT calculation. Therefore, the synergetic effect of the micro/nano-structure and electronic structure offers a simple, effective, and possible way for many other 2D materials to enhance their electrocatalytic HER activity.
