Fe 2 O s /γ-Al 2 O 3 catalyst was prepared by impregnation method and characterized by powder X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and test results show that, Fe203 crystal was compounded on γ-Al 2 O 3 carrier. Fe 2 O 3 /γ-Al 2 O 3 /H 2 O 2 and Fe 2 O 3 /γ-Al 2 O 3 /H 2 O 2 /UV processes were tested and optimized to remediate organic material of phenol. An initial phenol concentration of 250mg/L was used as representative of a phenolic industrial wastewater. The experiment optimized the effects of preparation conditions on behaviors of Fe 2 O 3 /γ-Al 2 O 3 catalyst and the processes to degrade phenol in aqueous environments. The experimental results showed that the removal of phenol with Fe 2 O 3 /γ-Al 2 O 3 /H 2 O 2 /UV was more complete than with Fe 2 O 3 /γ-Al 2 O 3 /H 2 O 2 and degradation of phenol can reach 94.7% after the reaction for 2 h.
