Spectroscopic Investigations of [FeFe] Hydrogenase Maturated with [57Fe2(adt)(CN)2(CO)4]2–

“…The industrial method for production of Fe(CO) 5 involves the direct carbonylation of Fe metal at high temperatures and pressures, e.g., 175 atm at 150 °C. 15 Such reactions require specialized autoclaves, 16 which are not suited for producing small amounts of 57 Fe(CO) 5 . A variety of laboratory syntheses of 57 Fe(CO) 5 have been described, but they suffer from low yields and difficult separations even when using specialized equipment.…”

Cellular transport and homeostasis of essential and nonessential metals

“…Additionally, iron (III) chloride is used in water purification and sewage treatments, paint and animal feed additives, fabric dyes. Iron (II) sulfate is the form of Fe used in fortified foods, whereas iron(III) sulfate can be used to pull down sewage minerals from tank water 18 . Fe is essential for normal physiological processes, considering Fe-bound hemoglobin is necessary for the transport of oxygen in blood.…”

Stabilizing Metallic Iron Nanoparticles by Conformal Graphitic Carbon Coating for High-Rate Anode in Ni–Fe Batteries

“…In such a process, iron pentacarbonyl (Fe­(CO) 5 ) was directly pyrolyzed at 250–300 °C under ambient pressure to generate Fe particles following the reaction Fe­(CO) 5 →Fe + 5CO. While controlling the pyrolysis conditions (e.g., temperature, pressure), various types of Fe particles can be made for other applications; they were generally formed as microsize metallic Fe particles or with surfactant coatings which were not favorable for making Ni–Fe battery anodes . By comparison, using an aerosol-assisted pyrolysis, − Fe nanoparticle with an in situ formed protective surface coating can be easily obtained without metallic Fe being oxidized.…”

“…By comparison, using an aerosol-assisted pyrolysis, − Fe nanoparticle with an in situ formed protective surface coating can be easily obtained without metallic Fe being oxidized. As shown in Scheme , in step I Fe­(CO) 5 is partially hydrolyzed under the alkaline condition with the Hieber-base reaction to yield iron carbonyl hydride with its salt as below (eq ) …”
