Synthesis of magnetic CuFe₂O₄/Fe₂O₃ core-shell materials and their application in photo-Fenton-like process with oxalic acid as a radical-producing source

In this work, we proposed to synthesize CuFe2O4/Fe2O3 core-shell materials with different Fe2O3 contents in order create new and efficient photo-Fenton-like catalysts for the degradation of methylene blue oxalic acid as a radical-producing source. The were prepared through two stages: first, CuFe2O4 was by hydroxide coprecipitation – annealing method then, immobilized on surface simple impregnation procedure. According experimental results, our exhibit high catalytic activity under both UVA light visible light, well good ferromagnetic properties, which allows them be easily separated from solution magnet. Among them, catalyst molar ratio 1:2 showed best performance rate constant 2.103 h–1 0.542 2 times higher than sample. enhanced activities can attributed content Fe3+ species, specific area presence rod-like particles their surface.
