摘要
近几十年来,随着工业生产的不断发展,水体污染事件频发.纳米零价铁(nano zero-valent iron,nZVI)作为水体污染治理修复研究的热点材料之一而受到广泛关注.该综述基于CiteSpace 6.1.R6可视化软件,对Web of science核心合集数据库25年(1997-2022年)有关纳米零价铁在水体污染修复治理方面的文献进行检索,得到满足检索条件的2479篇文献并进行了可视化分析.结果表明:(1)25年来,纳米零价铁在水体污染修复治理方面的发展经历了初步探索期、缓慢发展期、迅速增长期的3个时期,发文量分别占总发文量的0.4%、14.5%和85.1%.(2)国家和机构之间的联系和合作较为密切,而作者之间的合作较为松散.(3)3个时期的研究热点各不相同,研究的主题不断拓宽,未来可能的研究热点是纳米零价铁的绿色低成本合成方法探究、纳米零价铁去除污染物原子尺度机理研究以及与微生物技术等联合处理复杂介质中的污染物等.
In recent decades,with the continuous development of industrial production,water pollution incidents have occurred frequently.Nanoscale zero-valent iron(nZVI)has received much attention as one of the hot materials for water pollution control.Based on the CiteSpace 6.1.R6 visualization software,this review covers Web of science core collection database for 25 years(1997—2022)for nZVI in water remediation.The results show that:(1)In the past 25 years,the development of nZVI in water pollution treatment has gone through three periods:the initial exploration period,the slow development period and the rapid growth period,with the number of publications accounting for 0.4%,14.5%and 85.1%of the total number of publications,respectively;(2)The connection and cooperation among countries and institutions are closer,while the cooperation among authors is looser;(3)The research hotspots of the three periods are different,and the research topics are constantly broadened.The potential research hotspots in the future are the exploration of green and low cost synthesis methods of nZVI,the study of atomic scale mechanism of nZVI to remove pollutants,and the joint treatment of pollutants in complex media with microbial technology.
