Abstract

Abstract: The rGO-CeO₂-Fe₂O₃ composite material has been prepared by hydrothermal method using graphene oxide as carrier. The composite material has been characterized by XRD,SEM,EDS and FT-IR,and its photo-catalytic degradation performance and mechanisms investigated. The results show that the catalytic degradation effect of rGO-CeO₂-Fe₂O₃ composite on the highly acidic dye wastewater is obviously better than that of rGO-CeO₂ and rGO-Fe₂O₃,and the dye degradation rate is as high as 97.64%,under UV irradiation for 30 min. The addition of rGO and CeO₂ has accelerated the charge transfer efficiency and reduced the electron-hole recombination rate,which significantly improves the photo-catalytic activity of Fe₂O₃.

Key words: rGO-CeO₂-Fe₂O₃, photo-catalytic, highly acidic dye wastewater

摘要： 以氧化石墨烯为载体，通过水热法制备rGO-CeO₂-Fe₂O₃复合材料。采用XRD、SEM、EDS和FT-IR对制备的复合材料进行了表征，并对其光催化降解性能和机理进行了研究。结果表明：rGO-CeO₂-Fe₂O₃复合材料对高酸性染料废水的光催化降解效果明显优于rGO-CeO₂和rGO-Fe₂O₃，紫外光照30 min，染料降解率高达97.64%。rGO和CeO₂的加入，加快了电荷传输效率，降低了电子-空穴复合率，明显提高了Fe₂O₃的催化活性。
