摘要/Abstract

摘要：

采用沉淀-沉积法制备了PdO/CeO₂催化剂, 并使用X射线衍射、高分辨透射电镜、N₂吸附-脱附等温线、X射线光电子能谱和Raman光谱对催化剂进行了表征. 表征结果显示, Pd在复合物中以Pd²⁺形式存在; PdO和CeO₂间的相互作用提高了CeO₂中的Ce³⁺含量. 通过酸性橙7和水杨酸的类芬顿降解考察了PdO/CeO₂的多相类芬顿和可见光芬顿催化活性. 结果表明, PdO沉积显著地促进了水杨酸的类芬顿降解, 催化剂的PdO含量为1.0 at%时其活性最佳. 染料酸性橙7在可见光照射条件下会引发染料光敏化效应. 吸附的染料分子在光激发后通过界面电子注入促进了Ce³⁺自表面过氧物种的再生. 由此, PdO负载和可见光照射的共同作用下, 1.0 PdO/CeO₂催化剂的酸性橙7类芬顿降解速率常数为3.90 h^-1, 为纯CeO₂活性的50倍左右.

Abstract:

A PdO/CeO₂ catalyst was prepared by deposition-precipitation method and characterized with X-ray diffraction, high-resolution transmission electron microscopy, N₂ adsorption-desorption, X-ray photoelectron spectroscopy and Raman spectroscopy. The results show that the Pd is presented as Pd²⁺ in the catalyst. The interaction between the deposited PdO and CeO₂ increases the Ce³⁺ content. The catalytic activity of PdO/CeO₂ was tested in the heterogeneous Fenton-like degradation of acid orange 7 (AO7) and salicylic acid (SA), both in the dark and under visible irradiation. Deposition of PdO accelerates the Fen-ton-like degradation of SA, which reaches a maximum at 1.0 atom% PdO loading. A dye sensitization effect was seen with AO7 under visible irradiation. Dye sensitization promotes the regeneration of Ce³⁺ by interfacial peroxides species through interfacial electron injection. Consequently, the combined effects of PdO loading and visible light irradiating enhanced the Fenton-like activity to a reaction rate constant of 3.90 h^-1 for the 1.0 PdO/CeO₂, a ca. 50-fold improvement.
