General description

Iron(III) chloride is brownish to black crystalline solid that is highly soluble in water. As a moderately strong Lewis acid, it highly reactive with bases and capable of forming complex ions. It is widely used as a iron precursor in the field of catalysis, solar cells and batteries.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Iron(III) chloride can be used:
  • As a precursor to fabricate nano-sized Fe-N-C catalysts for proton exchange membrane(PEM) fuel cells. FeCl3 iron precursor, helps to achieve the lowest charge transfer resistance and high peak power density.
  • As an oxidant to prepare FeOCl@PPy cathode materials for Li-ion batteries with good cycling stability.
  • As a precursor to fabricate amorphous multifunctional am-Fe–Bi/NF electrode for rechargeable Zinc-air batteries.
  • To synthesize Fe3O4@nanocellulose/TiCl nano fillers for dye-sensitized solar cells to reduce the crystallinity of the polymer.

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resitance properties.
