Influence of capping agents additives on morphology of CeVO4 nanoparticles and study of their photocatalytic properties

In this paper, cerium vanadate (CeVO4) nanoparticles were synthesized via a precipitation method on the reaction between cerium nitrate hexahydrate and ammonium metavanadate in water. Besides, three capping agents such as glucose, lactose and starch were used to investigate their effects on the morphology and particle size of CeVO4 nanoparticles. According to the vibrating sample magnetometer, cerium vanadate (CeVO4) nanoparticles indicated a paramagnetic behavior at room temperature. To evaluate the catalytic properties of nanocrystalline cerium vanadate, the photocatalytic degradations of methyl orange under ultraviolet light irradiation were carried out. The structural, morphological, magnetic, and optical properties of as-obtained products were characterized by techniques such as XRD, SEM, EDX, VSM, and UV-Vis spectroscopy.
