Fe–Mn binary oxide incorporated into diatomite was prepared by the redox reaction of KMnO4 and FeSO4.7H2O in range of pH of 3-9. The obtained catalyst was characterized by SEM, EDX and XPS. The results showed that manganse oxide and iron oxide exist multiple oxidation states including Mn2O3, MnO2, FeO and Fe2O3. The Mn-Fe-diatomite exhibited catalytically synergized properties of iron and manganese oxide. The phenol oxidation by H2O2 using...
