Preparation of Fe/γ-Al₂O₃ Catalyst by Ultrasonic Infiltration and Catalytic Degradation of Formaldehyde Wastewater

Abstract:

γ-Al₂O₃ was used as carrier and Fe/γ-Al₂O₃ catalyst were prepared by wet impregnation and ultrasonic infiltration method and characterized by specific surface area and pore distribution (BET), scanning electron microscope (SEM), energy dispersive spectrometer (EDS) and x-ray diffraction (XRD). Specific surface area of Fe/γ-Al₂O₃ catalyst was 224.93m²/g from BET analysis. Active component of catalyst was attached on the surface of carrier from the characterization of SEM and EDS. The prepared catalyst was used for the catalytic degradation of formaldehyde wastewater. The results indicated that the efficiency of H₂O₂/Fe/γ-Al₂O₃ catalytic oxidation was better than Fe/γ-Al₂O₃ catalytic oxidation and H₂O₂chemical oxidation.
