摘要：

The FeVO4 nanoparticles were synthesized by a precipitation process. The FeVO4 nanoparticles were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis diffuse reflectance spectroscopy (DRS). It was found that the prepared FeVO4 nanoparticles show an average grain size of 50-80 nm in diameter, and strong visible-light absorption with absorption onset of 515 nm, indicating a narrow optical band gap of 2.4 eV. Consequently, the FeVO4 nanoparticles show high visible-light photocatalytic activity for decomposition of methyl orange.
