Abstract

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.
