THE USE OF INTERCALATION COMPOUNDS OF ALUMINUM HYDROXIDE FOR THE PREPARATION OF NANOSCALE SYSTEMS

Intercalation compounds of lithium-aluminium double hydroxide (LADH) [ LiAl2(OH)(6)](n)X . pH(2)O, X-[CuEdta](2-), [CoEdta](2-), [NiEdta](2-) , [Fe(CN)(6)](3-) were obtained. Thermal decomposition of LADH-interca lates with complexes of transition metals and Edta leads to the dehydr ation and dehydroxylation of the hydroxide matrix and to the collapse redox process of the complex anion with the appearence of nanoscale me tal particles distributed in a dielectric matrix. Photolysis of [LiAl2 (OH)(6)](3)[Fe(CN)(6)]. nH(2)O leads to the formation of nanoscale sys tems containing two-dimensional lithium-aluminium hydroxide packets se parated by [Fe(CN)(6)](4-) complexes and [Fe-x(OH)(6-x)]((3+x)-) clust ers.
