In this work, the synthesis and characterization of cobalt ferrite nanoparticles (CoFe2O4 NPs) were carried out. The characterization studies confirmed that the synthesized particles were determined to be magnetic CoFe2O4 NPs in nanoscale and cubic spinel structure. The Brunauer–Emmett–Teller specific surface area of mesoporous CoFe2O4 NPs was determined to be 145.03 m2/g. The photo Fenton-like degradation ability of CoFe2O4 NPs was also evaluated and the results demonstrated that the synergistic effect of combining of Co and Fe2O4 enabled CoFe2O4 NPs to become the promising photo Fenton-like catalyst for degradation of methylene blue (MB) from aqueous solutions. At the optimum experimental conditions (3.0 of initial pH, 25 mM of H2O2 concentration, 50 mg/L of initial dye concentration, and 0.25 g/L of catalyst concentration), 18.29% chemical oxygen demand removal and 99.75% color removal were achieved after the photo Fenton-like degradation of MB in the presence of CoFe2O4 NPs heterogeneous catalyst with near-UV radiation.
