Abstract :For the removal of toxic organic phenol pollutants, to find a new alternative oxidation catalyst has been an important topic for a long time. Iron terephthalate insert ignore into journalissuearticles values(MIL-53); is an efficient catalyst for oxidation processes with high porosity and high surface area. In this study, MIL-53 was used for the oxidation of phenol. The catalyst was synthesized by hydrothermal method at 150°C for 2 h. It was structurally characterized by FT-IR and p-XRD. Thermal properties were also examined. The surface area was found as 152 m2 /g with micropore areas. The liquid phase oxidation of phenol by hydrogen peroxide was performed on MIL-53. The reaction time, reaction temperature, catalyst amount and oxidant amount were also investigated. The phenol was removed with 91% conversion for 3 hours at 80°C. MIL-53 was enhanced as an alternative catalyst for liquid phase oxidation of phenol with high efficiency, selectivity, and conversion.
