Abstract

Copper ferrite nanoparticles were synthesized by sol-gel auto-combustion method and characterized by XRD, SEM, FT-IR and UV-Vis. Powder XRD analysis and FT-IR spectroscopy confirmed the formation of ferrite spinel phase. The crystallite size was calculated to be 77 nm using Scherrer’s equation. The morphology and size of the synthesized nanoparticles have been observed by scanning electron microscopy. The energy band gaps were calculated from DRS data. Dye degradation of Direct Red 264 was carried out by CuFe2O4 as a catalyst under UV lamp. Langmuir, Toth and Fritz-Schlunder isotherms were studied in photocatalytic degradation.
