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[1]. In addition, zero-valent iron is also used is also used as caatalyst for Fenton oxidation 2,4-dichlorophenol [2]. Iron(II) sulfate heptahydrate is used as a catalyst for greener amide bond formation from amines and aldehydes[3]. 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[4]. 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[5]. 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.[6]
