High activity of ZnFe2O4 nanoparticles for photodegradation of crystal violet dye solution in the presence of sunlight

Abstract

Using the co-precipitation oxidation method and metal salt precursors, pure MFe2O4 (M = Co, Zn, Cu and Ni) photocatalysts were prepared co-precipitation method. The several properties of photocatalysts were studied. In sunlight and at neutral pH, all photocatalysts degraded crystal violet and performance ranking was NiFe2O4 < CoFe2O4 < CuFe2O4
