Selective synthesis and growth mechanism of CeVO4 nanoparticals via hydrothermal method

Abstract Selective-controlled structure and shape of CeVO 4 nanocrystals were successfully synthesized via a hydrothermal method from Na 3 VO 4 ·12H 2 O and Ce(NO 3 ) 3 ·6H 2 O. The resulting products were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM) and energy dispersive spectroscopy (EDS). The influence of hydrothermal temperature, precursor solution concentration on the crystal and morphology of products were further studied. The results showed that the as-synthesized products exhibited pure single-crystal CeVO 4 nanoparticles with tetragonal structure. The hydrothermal temperature and precursor solution concentration had important effects on the formation of CeVO 4 nanoparticles. Furthermore, the growth mechanism of CeVO 4 nanoparticles was explained with Ostwald ripening mechanism.
