• mineralization rate of about 60% in 60 min and great recyclability with a recycle efficiency of 86.78% after five runs for MB. The probable mechanism of this catalytic system is also proposed as a synergistic effect between MnO2 and Fe3O4. Keywords: diatomite; Fenton-like oxidation; hybrid catalyst; iron(II,III
