Abstract

Abstract Novel ferrous tungstate (FeWO 4 ) microspheres have been first synthesized via a ethylene glycol (EG)-assisted solvothermal process in the presence of reactable ionic liquid 1-octyl-3-methylimidazolium tetrachloroferrate [Omim]FeCl 4 . The as-prepared FeWO 4 materials were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscope (EDS), Transmission electron microscopy (TEM), X-ray photoelectron spectra (XPS), diffuse reflectance spectroscopy (DRS) and photocurrent. During the preparation process, [Omim]FeCl 4 played important roles as reactant and template at the same time. Moreover, the photocatalytic activities of FeWO 4 microspheres were evaluated on the degradation of Rhodamine B (RhB) under visible light irradiation. FeWO 4 microspheres exhibited a significant improved photocatalytic performance for degradation of RhB under visible light irradiation. A possible mechanism of FeWO 4 on the enhancement of visible light performance was proposed.
