Application

Iron(II) sulfate heptahydrate, 99.99% trace metal basis is widely used in the synthesis of iron oxide, core shell Fe-Fe₃O₄ Nanostructures. These nanostructures were successfully used to trigger the sulphate radical oxidation of methyl orange (MO) in an aqueous solution by activating sodium persulfate. In addition, zero-valent iron is also used is also used as caatalyst for Fenton oxidation 2,4-dichlorophenol . Iron(II) sulfate heptahydrate is used as a catalyst for greener amide bond formation from amines and aldehydes. Moreover, iron(II) sulfate heptahydrate has been also used as an inexpensive and environmentally friendly catalyst, at room temperature for the four component Synthesis of Protected Homoallylic Amines. Iron(II) sulfate heptahydrate is also used as an important precursor for the synthesis of electrode materials for Battery. For example: The monoclinic form of FeOHSO₄, synthesised from Iron(II)sulfate heptahydrate, has been used as a positive electrode material for rechargeable Li-ion batteries. In addition, Iron based flurophophate synthesised from Iron(II)sulfate heptahydrate also used as battery materials to increase the open-circuit voltage by manipulation of the oxidation state of 3d-metal through the electric effect of polyanion.
