Fe-MOFs were successfully synthesized with the dielectric barrier discharge (DBD) plasma method, and applied for degradation of methyl orange by the Fenton process. Fe-MOFs were characterized by XRD, SEM, EDS, BET and FT-IR. A systematic study was carried out to optimize the synthesis conditions, taking into account the Fenton capacity performance for degradation of methyl orange. The optimal synthesis conditions were a discharge time of 100?min, discharge voltage of 18 kV, reactant concentration of 14 g L ~(?1) and reactant mass ratio (TA?:?FeCl _(3) ·6H _(2) O) of 1?:?5, with influence on the crystallization, morphologies and particle size. The degradation rate of methyl orange could reach 85% within 40 min with the MO concentration of 50 mg L ~(?1) , Fe-MOF dosage of 0.12 g L ~(?1) , pH of 5 and H _(2) O _(2) at 1 mL L ~(?1) . Meanwhile, the Fenton catalytic process was conducted covering a range of catalyst concentrations, initial MO concentrations, pH and H _(2) O _(2) amounts. Higher catalyst concentration, lower MO initial concentration, pH of 3 and H _(2) O _(2) amount of 1 mL L ~(?1) were conducive to the degradation efficiency.
