In the present work, multi-layered mesh-like MoS2 hierarchical nanostructure was fabricated on a Ti foil in a hydrothermal process. Meanwhile, photocatalytic H-2 evolution from water over the as-prepared MoS2 hierarchical nanostructure was investigated under visible irradiation. The results indicate that the as-prepared MoS2 hierarchical nanostructure consists of the vertically grown few-layers MoS2 nanosheets. And this three-dimensional mesh-like MoS2 hierarchical nanostructure possesses high photocatalytic activity for visible-light-driven H-2 evolution from water. A rate of H-2 evolution of approximately 240 mu mol g(-1) h(-1) was achieved under optimal conditions. Furthermore, the photocatalytic mechanism was preliminarily discussed. (C) 2016 Elsevier B.V.
