I am currently working on the photocatalytic nanocomposites for water and waste water treatment. This project is based upon the development of nanocomposite of graphene oxide with core-shell Fe3
nanoparticles as nanosorbents for the removal of toxic ions and bacteria from water and waste water. The nanostructure composite developed for this purpose will consist of a mixture of functionalized graphene oxide and core-shell nanoparticles of Fe2
. In the past years it has been shown that graphene has a very high electrical conductivity of electron knows as ballistic behavior. Combination of this character with being hydrophilic in nature, will provide higher efficiency of the water purification process. The Fe3
and ZnO photocatalysts act as nanosorbents in UV-vis light and attract all the micro level impurities such as metal ions (e.g. Pb+2
) and dissolved minerals with chloride and sulfate ions. This nanocomposite is expected to be an excellent contribution in the field of water purification and separation.
