Abstract

The three-dimensional architectures often exhibit good functional properties. In current work, the unique WS2 nanoflowers self-assembled by nanosheets have been successfully synthesized via a novel hydrothermal method with the assistance of sodium silicate. A possible growth mechanism was further proposed in detail. The obtained WS2 nanoflowers showed a very excellent optical absorption properties and holds substantial promise for rendering WS2 as an excellent visible photocatalyst material. Such a synthetic way may open up an avenue to tailor the morphologies of some other transition metal disulfides and enhance their functional performance.
