General description

Iron(III) chloride is brownish to black crystalline solid that is highly soluble in water. As a moderately strong Lewis acid, FeCl3 can form complex compounds and adducts with Lewis bases, making it a useful catalyst in various chemical reactions.
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 prepare Fe(III)-chlorophyll complex. Fe(III) enhances the performance of chlorophyll as a dye sensitizer in DSSCs by forming complex compounds with metal-ligand charge transfer properties, leading to increased efficiency and improved paramagnetic properties.
  • As a catalyst /modifying agent to prepare high performance porous carbon for lithium-ion battery anodes. The addition of FeCl3 enhances the graphitization of porous carbon without significantly affecting the layer spacing and also the specific surface area and pore volume of porous carbon.
  • As a co-catalyst to fabricate liquid catalyzed fuel cell (LCFC) for direct conversion from carbohydrates to electricity. It helps to improve the hydrolysis of carbohydrate and enhances the electron transfer from carbohydrates to anode.

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.

Professor Randal Lee (University of Houston, USA) discusses design considerations for iron oxide magnetic nanospheres and nanocubes used for biosensing, including synthetic procedures, size, and shape. The effects of these variables are discussed for various volumetric-based and surface-based detection schemes.

Lithium-ion batteries represent a group of electrochemical devices used for electricity storage and have attracted a lot of attention in the past two decades due to their portability, rechargeability and low cost.
