摘要:

近年来, 纳米铁颗粒(纳米零价铁)因其优异的催化/还原性能, 并且价廉、环境友好, 已成为主要的环境修复材料之一。目前, 纳米铁颗粒主要用于水体修复, 如: 重金属离子去除、有机物污染物降解和无机阴离子催化还原等。纳米铁颗粒易团聚和结构单一等问题会导致其活性低、稳定性差和去除种类单一。为了克服上述问题, 迫切需要研究纳米铁颗粒的界面设计。本文重点阐述纳米铁颗粒及其复合材料的可控制备、界面设计、在重金属去除和硝酸根去除转化中的应用以及在环境修复中的未来发展方向。

Abstract:

Recently, iron nanoparticles have become one of the main research materials for environmental remediation due to the excellent catalytic/reduction performance, low cost and environmental friendliness. At present, the research of iron nanoparticles mainly focuses on the heavy metal removal, organic pollution degradation, inorganic anion catalytic reduction in sewage system, etc. However, there still exist some problems, such as low removal efficiency, poor stability, and single removal on account of several self-defects of agglomeration and tedious structures. Hence, this review focuses on the following aspects: 1) controllable preparation of iron nanoparticles; 2) interface design of iron composites; 3) application of iron nanoparticles in heavy metals removal and electrocatalytic denitrification; 4) prospect of iron nanoparticles composites in environmental remediation.

Key words: iron nanoparticles, interface design, adsorption application, environmental electrocatalysis, environmental remediation, review
