摘要：
Nano zero-valent iron (nZVI) has been considered to be one of the potential materials, however, its high activity makes it easy to corrosion in air and water and the formed passivation layer covering the surface of particle leads to reduction of the active sites. The researches indicate that the problem of oxidation, passivation and agglomeration of nZVI can be reduced by the modification method. This paper mainly introduces the coating, loading, bimetallic and sulphurization four modification methods, and the enhancement mechanism of modified nZVI is discussed. The application problem of modified nZVI is indicated and relevant suggestions are given for the problems. The nZVI composites prepared by various modification methods can not only reduce the agglomeration and improve the treatment effect of target pollutants, but also can solve the potential problems of biotoxicity. It also suggestes that one of the future research points is the size of nanoparticles and the stability of modified materials. © 2023 Chemical Industry Press. All rights reserved.
