In this research, CeVO 4 with 450 ☌ calcination showed the highest photocatalytic activity of 94.58% within 120 min under UV light irradiation because of the highest available surface active sites for photodegradation of MB under UV light irradiation.Īmeri, V., Eghbali-Arani, M., Pourmasoud, S.: New route for preparation of cerium vanadate nanoparticles with different morphology and investigation of optical and photocatalytic properties, J. The photocatalytic activity of the as-synthesized CeVO 4 nanoparticles was evaluated via the degradation of methylene blue (MB) under UV light irradiation. 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.
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.
