摘　　要：叙述了近年来纳米铁及其双金属材料的绿色合成方法,分析了用于纳米铁绿色合成的天然植物来源及活性成分的作用机制,总结了绿色合成纳米铁材料在水体污染物去除方面的应用进展。认为这一领域仍有很大的探索空间,应寻找更多适用于纳米铁高效合成的植物,采用相关技术识别天然活性成分,优化合成条件,明确绿色纳米铁的合成机制;调控绿色纳米铁的形态结构,提高其反应性和稳定性,探究绿色纳米铁对典型污染物的降解机理;加强绿色纳米铁在环境生态毒性和迁移转化规律领域的研究,以实现绿色纳米材料的大规模生产和污染物的原位修复。The green synthesis of iron nanoparticles and their bimetallic counterpart in recent years were reviewed. The phyto-resources and the role of natural active ingredients in the green synthetic iron nanoparticles were investigated, and their application on removal of aqueous pollutants was summarized. It appeared that many problems are still unsolved in this field, such as which plants were suitable for iron nanoparticles synthesis, and the active natural ingredients should be identified by specific technology. The optimized conditions and detailed mechanism of green synthetic iron nanoparticles were remained unclear. In order to explore the pollutants removal mechanism by green synthetic iron nanoparticles, the morphology and structure of green synthetic iron nanoparticles should be adjusted and controlled effectively to enhance their reactivity and stability in the degradation process. The research on the environmental ecotoxicity, migration and transformation of green synthetic iron nanoparticle should be further extended, so as to minimize the risks which obstacle the largescale production of green synthetic iron nanoparticles and their application of the in-situ remediation of contaminants.
