Redox Reactions in the Layer of Adsorbed Fe~(2+)and CrO_4~(2-)Ions and Synthesis of Fe~(3+)-Cr~(3+)Double Hydroxide Nanolayers by Ionic Deposition

摘要

Conditions for ionic deposition on a silica surface of Fe~(3+)-Cr~(3+)double hydroxide nanolyers.The synthesized nanolayers were studied by X-ray photoelectron spectroscopy(XPS),ellipsometry,electronic spectroscopy,and transmission FT-IR spectroscopy.Double metal hydroxides are known to be effective sorbents and ion exchangers.New possibilities of their synthesis are opened up by the ionic deposition method that allows hydroxide nanolayers to be deposited onto the surface of an inert support with a preset specific surface area.
