Preparation of Fe/γ-Al2O3 Catalyst by Ultrasonic Infiltration and Catalytic Degradation of Formaldehyde Wastewater Dan Wu1a, Xianpeng Zheng1,2, Yan Li1 and Qin Wei1 1School of Chemistry and Chemical Engineering, University of Jinan, Jinan 250022, China 2The Environmental Protection Agency of Lixia District, Jinan 250014, China aemail: chm_wud@ujn.edu.cn Keywords: Fe/γ-Al2O3, catalyst, catalytic degradation, 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).
BET, EDS and XRD techniques were used to investigate the structure of catalysts and catalytic degradation experiments.

It could not only solve the liquid leakage problem of paraffin effectively, but also the inorganic porous materials such as expanded perlite were chemistry stability, non-toxic and low price, so the composite phase change energy storage materials had a good economic benefit.
One was the internal porous structure of the expanded perlite was a kind of restriction system, which limited the space motion of paraffin molecules.
