Radiolytic reduction of Fe(II) in 2-propanol

The first reduction steps of iron (II) in 2-propanol have been studied by pulse radiolysis technique. The rate constant value of the reaction of solvated electron with iron (II) was found to be 4.8 × 109 dm3 mol−1 s−1. The absorption spectrum of Fe(I) with a maximum at 350 nm was determined. The radiolytic reduction of FeII in 2-propanol under an inert atmosphere leads to the formation of very small iron nanoparticles whereas under a CO atmosphere, the stable Fe(CO)5 complex is formed.
