MgFe2O4/Ag3VO4 composite photocatalysts were synthesized by a milling-calcining method. The results of Rhodamine B (RhB) photodegradation showed that the MgFe2O4/Ag3VO4 composite exhibited enhanced photodegradation activity under visible-light irradiation. The 0.2 wt.% MgFe2O4/Ag3VO4 calcined at 573 K exhibited the optimal photocatalytic behavior. Its maximum degradation rate was 5.4 times higher than that of Ag3VO4. Moreover, transient photocurrent-time was also investigated. Based on the results of the characterizations, the mechanism of enhanced photocatalytic activity is discussed. (c) 2012 Elsevier B.V.
