TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compounds: The metal alkoxides are selected from methoxides, ethoxides, isomers of propoxides, butoxides and pentoxides. The solvent is a mixture of at least 2 of hexane, toluene, xylene, methanol, ethanol and butanol.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The metal in metal alkoxides/acetylacetonates is selected from bivalent metal ions comprising Mg2+ and at least one of Ni2+, Cu2+, Co2+, Zn2+, Fe2+ and Mn2+ and from trivalent metal ions selected from Al3+ and at least one of Ga3+, Ni3+, Co3+, Fe3+, Mn3+, Cr3+, V3+, Ti3+, La3+ and In3+. The ratio of bivalent to trivalent metal ions is 1-5 (preferably 2-3).Preferred Process: The hydrolysis involves homogenization of metal precursors in hydrocarbon-alcohol solvent followed by controlled addition of stoichiometric amount of deionized water. The hydrothermal treatment is carried out at 100-300 degreesC and 50-150 atm. The reaction mixture is hydrothermally heated at 1 degreesC per minute to 260-280degreesC and kept for 5-10 minutes under 60-120 atm. The aging is preferably affected for 10-12 hours. The solvent mixture in vented out at supercritical conditions to obtain the nano LDH. The recovered solvent free aerogel is dried overnight to 120 degreesC to remove the traces of solvent. The obtained powder nanoparticles are treated with sodium carbonate/phosphate/chromate/ibuprofen and dichlorofenec solution at room temperature to self-assembled into normal self-assembled nanostructural LDH in the form of a hexagonal, fibrous, membrane or thin film. EXAMPLE - Magnesium turnings (2.4 g) were reacted with freshly dried methanol (100 ml) under argon flow by stirring. Dry toluene (300 ml) was added to the resultant magnesium methoxide solution and continued for 2 hours. Aluminum isopropoxide (10.235 g) was added to the resultant solution and stirred for 2 hours. Then stoichiometric amount of deionized water (4.85 ml) was added over 0.5 hour. This solution was kept under stirring overnight at room temperature. The resultant solution (pH less than 7) was heated in autoclave to 265 degreesC at 60-80 atm for 4 hours, kept for 10 minutes, vented to obtain an aerogel material and further dried at 120 degreesC to yield nanobinary Mg/Al (2/1) system.
