The detection of V–O and Ce–O stretching modes indicates the formation of tetragonal zircon-type CeVO 4 structure. Particle sizes of the products were 20–40 nm for CeVO 4 with 450 ☌ calcination and 80–120 nm for CeVO 4 with 500 ☌ calcination. The degree of crystallinity and size of the CeVO 4 sample were increased by the high growth rate of CeVO 4 nanoparticles at high temperature calcination. XRD patterns of the samples were indexed to tetragonal zircon-type CeVO 4 structure. The precursor shows two weight loss steps due to the evaporation and decomposition of absorbed water, tartaric acid, and nitrate constituent until at a temperature above 450 ☌. The as-synthesized products were characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy. J.CeVO 4 as UV light-driven photocatalyst was synthesized by sol-gel method using tartaric acid as a complexing reagent with subsequent calcination at 450–600 ☌ for 2 h in ambient air.
