| 针对经济快速发展导致的重金属环境污染问题，具备高比表面积、丰富官能团与发达孔隙结构的纳米氧化铁材料，因其低成本制备和环境友好特性，已成为水体和土壤重金属污染修复的研究热点。然而，纳米氧化铁在实际应用中存在易氧化、易团聚及表面活性不足等缺陷，特别是磁铁矿纳米材料氧化后分散性与磁性显著降低。本文综述了纳米氧化铁材料基于合成方法优化、表面修饰及复合材料构建等调控策略对其表面结构与物化特性的影响机制，深入解析材料在重金属污染修复中的去除机制与应用前景。研究表明，不同的调控策略可有效改变材料表面特性与性能，有望克服其固有缺陷，为纳米氧化铁材料的合成设计与重金属去除的应用提供了新途径。 |
| 英文摘要: |
| Iron oxide nanomaterials have become a focal point for remediating heavy metal pollution in water and soil due to rapid economic development. Their advantage lies in the high surface area, abundant functional groups, diverse pore structures, cost-effective synthesis and environmental friendliness. However, the practical application of iron oxide nanomaterials is hindered by several challenges, such as vulnerability to oxidation, tendency to agglomerate and low surface activity. These limitations are particularly evident in magnetite nanomaterials, which reduce their dispersivity and magnetic properties due to oxidation. This work reviews the control strategies for iron oxide nanomaterials, focusing on synthesis optimization, surface modification, composite construction and their effects on surface structure and physicochemical properties. The removal mechanisms and applications of iron oxide nanomaterials in the remediation of heavy metal contamination were also explored. The findings indicate that various control strategies can effectively enhance the surface characteristics and properties of iron oxide nanomaterials, overcoming their inherent limitations. These insights provide valuable insights for the synthesis, design and implementation of iron oxide nanomaterials in the remediation of heavy metal contaminants. |
