A magnetic cobalt ferrite (CoFe2O4) nanoparticles synthesized via a simple hydrothermal method using FeCl3 center dot 6H(2)O and CoCl2 center dot 6H(2)O as precursors and glycerol as a stabilizing agent. We have studied the effect of pH on the microstructure and photocatalytic performance of CoFe2O4 nanoparticles. The prepared samples were characterized by X-ray powder diffraction (XRD), diffuse reflectance UV-vis spectroscopy (DRS), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and measurement of the surface area using N-2 adsorption-desorption. The photocatalytic degradation of indigo carmine dye (IC) was evaluated under visible irradiation. The photocatalytic activity was found to be affected by the structural and optical properties as well as the surface area of the samples. The CoFe2O4 prepared at pH10 exhibited the highest photocatalytic activity for the degradation of indigo carmine dye. The synthesized CoFe2O4 can be potentially used as a visible-light responsive magnetically separable photocatalyst for wastewater treatment by magnetic separation.
