摘要：

Nanosized tungsten disulfide (WS2) sensitized titanium dioxide (TiO2) was successfully prepared via a simple yet facile hydrothermal process. The nanocomposite exhibited a wide and intensive absorption in the visible light region of 400-700 nm, and may have a potential application as a visible photocatalyst. In addition, the sensitization mechanism of the nano-WS2 was proposed to elaborate the wide visible light absorption of the WS2/TiO2 nanocomposites. (C) 2014 Elsevier B.V. All rights reserved.
