Nickel<span> ferrite </span>nanoparticle as a magnetic catalyst: Synthesis and dye degradation

Abstract

The aim of this work is the synthesis of NiFe 2 O 4 nanoparticles to catalyze photodegradation of direct red 264 under visible light. So, NiFe 2 O 4 nanoparticles were synthesized by a sol-gel autocombustion method. The catalyst was characterized by XRD, SEM, FT-IR and DRS. The effect of NiFe 2 O 4 nanoparticles as a catalyst was studied on photocatalytic degradation of Direct Red 264 (DR264) in typical wastewater using visible light irradiation. UV-vis spectrophotometer was used to measure concentration of dyes before and after degradation.
