To conquer the disadvantage of low photocatalytic efficiency resulted from narrow photoresponse range and electron-hole recombination, a 2D nanoplate-like MoS 2 /Bi 2 WO 6 heterojunction photocatalyst was designed and prepared by a facile two-step hydrothermal technique. Compared with pure Bi 2 WO 6 , the MoS 2 / Bi 2 WO 6 composite displayed an enhanced photoabsorption in the whole visible light region. Through the photodegradation of rhodamine B (RhB) under visible light irradiation (λ>400 nm), the photocatalytic activities of the obtained products were evaluated and the MoS 2 /Bi 2 WO 6 composite exhibited higher photocatalytic performance than that of pure Bi 2 WO 6 . The enhanced photocatalytic performance was attributed to the broad photoabsorption and low charge recombination driven by the photogenerated potential difference formed at the MoS 2 /Bi 2 WO 6 heterojunction interface.
