In this work, a template-free hydrothermal strategy has been developed to fabricate 3D hierarchical MoS2 microflowers on macroporous Ti mesh (MoS2 MF-Ti) as a binder-free electrode for hydrogen evolution reaction (HER). It is found that the Ti mesh is able to provide an ideal platform for self-assembly of the MoS2 nanosheets into the hierarchical microflowers. The as-prepared MoS2 MF-Ti electrode is characteristic of meso/macro porous structures, abundant active edges and good conductivity. As a result, the MoS2 MF-Ti demonstrates greatly enhanced electrocatalytic activity and stability toward HER due to its desirable structural features.
