Abstract

A simple and efficient method has been established for the synthesis of cerium orthovanadate (CeVO4) nanoparticles without the use of any catalysts or templates. Using Ce(NO3)3•6H2O and NH4VO3 as main material, the CeVO4 nanoparticles were synthesized by ultrasound method at 60°C and different pH conditions, The samples were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR) and UV-visible diffuse reflectance spectroscopy (DRS). The results showed that the pure CeVO4 of tetragonal structure was successfully synthesized at the pH=4, 6 and 8. The CeVO4 nanoparticles which were prepared at the pH=8 had an average grain size of 10~20 nm in diameter and the optical absorption onset of 355 nm, indicating the optical band gap of 3.49 eV. The photocatalytic activities of the CeVO4 nanoparticles have been evaluated by studying the degradation of methyl orange (MO). The results showed that CeVO4 nanoparticles appeared high photocatalytic activity for the decomposition of MO.
