Abstract
To conquer the disadvantage of low photocatalytic efficiency resulted from narrow photoresponse range and electron-hole recombination, a 2D nanoplate-like MoS2/Bi2WO6 heterojunction photocatalyst was designed and prepared by a facile two-step hydrothermal technique. Compared with pure Bi2WO6, the MoS2/ Bi2WO6 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 MoS2/Bi2WO6 composite exhibited higher photocatalytic performance than that of pure Bi2WO6. The enhanced photocatalytic performance was attributed to the broad photoabsorption and low charge recombination driven by the photogenerated potential difference formed at the MoS2/Bi2WO6 heterojunction interface.
