Synthesis of Nanocrystalline FeVO₄ and Its Visible-Light Photocatalytic Activity

Abstract:

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.
