摘要
In this research article, ZnO-Al2O3-CeO2-Ce2O3 mixed metal oxides phases were prepared by calci-nation of Zn-Al/Ce-CO3 layered double hydroxides (LDH) precursors, and evaluated for the photo-catalytic degradation of methyl orange (MO) as a model textile dye from aqueous solution under UV irradiation. First, Zn-Al-CO3 and a series of Zn-Al/Ce-CO3 with different Ce content (5,10, 15, 20%) were synthesized through co-precipitation method at Zn/(Al thorn Ce) molar ratio (r) of 3, then subjected to calcination at 500 degrees C for 6 h. Samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy coupled with energy dispersive X-ray analysis and pH point of zero charge. The experimental results of the photodegradation reveal that the photocatalyst developed from Zn-Al-Ce10%-CO3 LDH exhibits the highest photocatalytic activity, with a degradation efficiency of 99.8% after 300 min of irradiation. This performance was mainly ascribed to the presence of difference state of Ce, leading a highest separation efficiency of electrons and holes. The recycling tests suggests a much high photostability and reusability of the photocatalyst. (C) 2021 Elsevier Ltd. All rights reserved.
