Synthesis of sulfide Nano composites using Na-4 mica template

Various Nano composites were synthesized using mica crystallites medium. In some cases by oxidation or sulfidation treatment a core shell nanostructure could be generated. Nickel sulfide core shell Nano rod exhibited a number of optical absorption peaks which arose because of their structural characteristics.Nikel sulfide nano wire of diameter, 20 nm, were grown within nano channels of Na-4 mica.
