零价铁转化卤代有机物是环境修复的最新创新技术之一。例如，铁可用于在受污染的地下水羽流的路径上建造反应墙，以降解HOCs。本文提出了一种合成纳米级（1-100 nm）铁和钯化铁颗粒的有效方法。纳米级颗粒的特征在于高表面积与体积比和高反应性。合成的金属颗粒的BET比表面积为33.5m2/g。相比之下，市售的Fe粉末（
Transformation of halogenated organic compounds (HOCs) by zero-valent iron represents one of the latest innovative technologies for environmental remediation. For example, iron can be used to construct a reactive wall in the path of a contaminated groundwater plume to degrade HOCs. In this paper, an efficient method of synthesizing nanoscale (1-100 nm) iron and palladized iron particles is presented. Nanoscale particles are characterized by high surface area to volume ratios and high reactivities. BET specific surface area of the synthesized metal particles is 33.5 m(2)/g. In comparison, a commercially available Fe powder (
