Vertically Aligned Ultrathin 1T-WS2 Nanosheets Enhanced the Electrocatalytic Hydrogen Evolution.

ABSTRACT: Efficient evolution of hydrogen through electrocatalysis holds tremendous promise for clean energy. The catalytic efficiency for hydrogen evolution reaction (HER) strongly depends on the number and activity of active sites. To this end, making vertically aligned, ultrathin, and along with rich metallic phase WS2 nanosheets is effective to maximally unearth the catalytic performance of WS2 nanosheets. Metallic 1T polymorph combined with vertically aligned ultrathin WS2 nanosheets on flat substrate is successfully prepared via one-step simple hydrothermal reaction. The nearly vertical orientation of WS2 nanosheets enables the active sites of surface edge and basal planes to be maximally exposed. Here, we report vertical 1T-WS2 nanosheets as efficient catalysts for hydrogen evolution with low
