| 中文摘要: |
| 过渡金属同晶替换的铁氧化物因其具有稳定、高效和可重复利用等特点被广泛应用于催化处理难降解有机物领域。本文综述了这种新型催化剂的制备过程、过渡金属的同晶替换对催化剂物理化学性质(如比表面积、表面羟基数量、铁离子溶出量及热稳定性)的影响以及促进非均相Fenton反应的催化机制(氧化还原电对结构及氧空位理论)。最后,本文还探讨了这种新型铁氧化物在难降解有机物处理中的应用进展,为后续研究提供了新的思路。 |
| 英文摘要: |
| Due to the excellent stability, high efficiency, and favorable reusability, iron oxides isomorphous substituted by transition metals have been widely used in the degradation and mineralization of recalcitrant organic compounds. This paper reviews the preparation process of this novel catalyst, the effects of substituted transition metals on its physicochemical properties (such as specific surface area, surface hydroxyl amount, iron leaching, and thermostability), and the mechanisms underlying acceleration of heterogeneous Fenton reaction (such as the redox pairs and oxygen vacancies mechanisms). Finally, the applications of iron oxides doped with transition metals to degrade recalcitrant organic compounds are also discussed, and these results provide some new ideas for future study. |
