General description

Iron(0) pentacarbonyl is a straw-yellow to brilliant orange liquid soluble in organic solvents. It is widely used as a precursor for synthesizing iron oxide nanoparticles, which have applications in the field of energy conversion and storage due to their catalytic properties and ability to enhance electron transport.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for catalytic efficiency. Click here for more information.

Application

Chemical Synthesis of Monodisperse Magnetic Nanoparticles
Iron(0) pentacarbonyl can be used:
  • To fabricate Fe-based anode materials for high-performance aqueous secondary Ni−Fe batteries. It helps to achieve good safety, high power density, long term-life cycle, and high energy density.
  • As a precursor to synthesize highly stable, colloidal magnetic iron nanoparticles with narrow size distribution. These nanoparticles are potential candidates for MRI contrasting agents and magnetically separable catalysts.
  • To synthesize zero valent sustainable iron nanocatalysts for reduction reactions.

Reactant for:
  • Addition reactions
  • Decomposition via photolysis
  • Preparation of magnetic Fe onion-like fullerene micrometer-sized particles of narrow size distribution via thermal decomposition
  • Preparation of a heptanuclear iron carbonyl cluster used in catalytic hydrosilane reduction of carboxamides

  • Precursor for preparation of Fe nanoparticles for photocatalytic hydrogen evolution under highly basic conditions
