摘　　要：纳米零价铁(nZVI)颗粒由于其特殊的供电子特性,可用于还原、催化、吸附和降解广泛的污染物,是各种环境应用的重要材料。nZVI的传统制备方法是采用硼氢化钠作为还原剂。由于其昂贵的化学合成材料以及其毒性和副产物生成都会限制其应用。近年来,利用从植物提取物中的生物活性物质还原Fe^(3+)或Fe^(2+)替代化学合成受到了人们的广泛研究。综述了近年来利用植物提取物合成的nZVI及其复合材料对各种污水的吸附降解应用,探讨了目前存在的挑战,展望其发展趋势。Zero-valent iron(nZVI)nanoparticles are important materials for a variety of environmental applications due to their special electron-donating properties for reduction,catalysis,adsorption and degradation of a wide range of pollutants.nZVI has been traditionally prepared using sodium borohydride as a reducing agent.Its application can be limited by its expensive chemically synthesized material as well as its toxicity and by-product generation.In recent years,the use of biologically active substances from plant extracts to reduce Fe^(3+)or Fe^(2+)instead of chemical synthesis has been widely investigated.nZVI and its composites synthesized from plant extracts in recent years were reviewed for adsorptive degradation applications of various effluents,the current challenges were discussed,and its perspectives were put forward.
