Abstract: Photocatalysis as an emerging advanced oxidation processes have enormous merits in environment purification area. The novel FeWO4@ZnS heterostructure microspheres were fabricated by a two-step hydrothermal method and the analysis of SEM and XRD shown that the ZnS microspheres were assembled by small ZnS nanoparticles. EDS elements mapping shown that the FeWO4 nanoparticles were uniformly loa-ded on the surface of ZnS microspheres. The photocatalytic performance towarding to the azo dye MB and newly-developing TC were conducted in the case of UV-visible light, visible light and photo-Feton system. Results indicated that the heterostructure microspheres exhibits better activity compared with pure samples in three different system. The enhancement of photocatalytic can attributed to the presence of heterostructure which restrains the recombination of photoinduced electrons and holes and accelerates the interface transfer of photogenerated carriers. In addition, the possible electrons transfer mechanism of enhanced photodegradation performance were proposed. This novel and efficiency FeWO4@ZnS heterostructure photocatalyst may possesses potential application in the future environmental purification area.
