摘要

铁(II)-铁(III)层状双氢氧化物(绿锈)由于其软还原性能和降低各种溶解无机物种迁移速率的能力，在环境系统中起着重要作用。将露天体系中钢表面初步形成的羟基碳酸盐绿锈与HAuCl - 4水溶液接触，得到了fefe2o4和au0的核壳型纳米复合材料。纳米复合材料的形成伴随着第二鳞片晶相的出现。纳米复合粒子具有超顺磁性，具有独特的生物等离子体特性，在生物医学领域具有广阔的应用前景。

Formation of core&shell type nanocomposites based on the Fe(II)-Fe(III) layered double hydroxides

Fe(II)-Fe(III) layered double hydroxides (Green Rust) play an important role in the environmental systems due to their soft reductive properties and capacity to decrease the migration rate for various dissolved inorganic species. The core&shell type nanocomposites FeFe 2 O 4 &Au 0 were obtained when the hydroxycarbonate Green Rust, that was preliminary formed on the steel surface in the open-air system, was contacting with HAuCl 4 water solution. The formation of the nanocomposites was accompanied by the appearance of the second lepidocrocite phase. The nanocomposite particles belong to superparamagnetics and they showed the unique bioplasmonic properties that will be perspective for the bio-medical application in the future.
