Abstract

The CoFe2O4, NiFe2O4 and MgFe2O4powderswere prepared using wet method.XRD, AFM, and UV-Vis spectrophotometer were used to determine the structure and morphology of the samples, as well as photocatalytic activity to degradethe methylene blue (MB) dye. The samples were exposed to a 2 hours heat treatment at 700°C. CoFe2O4, NiFe2O4 and MgFe2O4had average crystalline sizes of 32.5 nm, 34.7 nm, and 35.3 nm, respectively, while magnetic saturation magnetizations of 84.4 emu/g, 48.1 emu/g, and 26.06 emu/g, respectively
