Abstract: Bimetallic copper-iron organic frameworks （Cu/Fe-MOFs） were synthesized by one-step method at room temperature.Then the precursors were annealed to obtain CuFe₂O₄@C catalysts.The structure and composition of as-prepared samples were characterized by using TG-DTG,XRD,XPS and SEM.The effects of annealing temperature,phenol substrate concentration,catalyst dosage and reaction temperature on the removal effect of phenol and COD were systematically studied by univariate variable method.The results show that CuFe₂O₄@C is formed by high temperature annealing of Cu/Fe-MOFs,which almost maintains the strucutre of the MOF precursor.XPS further demonstrates the coexistence of Fe（Ⅱ）,Fe（Ⅲ）,Cu（Ⅰ）and Cu （Ⅱ）,which is beneficial to the catalytic reaction.The phenol removal rate is 97.6% and the COD removal rate is over 96% at annealing temperature of 700℃,substrate concentration of 100 mg/L,catalyst dosage of 20 mg and reaction temperature of 220℃ for 180 min.The reaction mechanism is presumed to be that the metal ions in the system form a complete redox process during the reaction with oxygen and phenol,and the phenol is continuously decomposed into CO₂ and H₂O by the production of·O₂^-,·OH^-and other reactive substances under the condition of sufficient oxygen.
