In this, work, a series of REVO4 (RE = La, Pr, Nd) nanoparticles were successfully fabricated by the hydrothermal method. The as-synthesized REVO4 nanoparticles were characterized by various techniques of X-ray diffraction (XRD), scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX). The photocatalytic activities of obtained products were investigated by photodegradation of moderacid red RS and direct yellow GX under visible light. The NdVO4 photocatalyst showed higher discoloration of organic dyes than LaVO4 and PrVO4. About 64% moderacid red RS was degraded within 150 minutes catalyzed by the catalyst NdVO4.
