Photocatalytic Degradation of Organic Pollutants over MFe₂O₄ (M = Co, Ni, Cu, Zn) Nanoparticles at Neutral pH.

ABSTRACT: In this study, we report a surfactant-mediated synthesis of ferrites (MFe₂O₄: M = Co, Ni, Cu, Zn) using the co-precipitation-oxidation method. The band gap calculated from UV-Visible diffuse reflectance spectra were found in the range of 1.11-1.81 eV. These ferrite nanocatalysts were studied for the photocatalytic degradation of multiple organic dyes in a 32 W UV-C/H₂O₂ system. All the four ferrites showed an excellent dye degradation rate in the range of 2.065-2.417 min^-1 at neutral pH. In the optimized condition, NiF was found to degrade 89%, 92%, 93%, and 78% of methylene blue, methyl orange, bromo green, and methyl red, respectively within 1 min of UV-irradiation. A 40% TOC removal was recorded after 5 min of degradation reaction,
