| 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. |
| Application: | 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. |
| 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. |
