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.
