Abstract

We investigated the oxidation enthalpy of nanophase Fe clusters with an average diameter of 6 nm produced using a multiphoton decomposition method of Fe(CO) ₅ in the presence of argon and the photosensitizer SF ₆. The quantum yield of the multiphoton decomposition process was so extremely high that the decomposition reaction completed in a short time, i.e., less than 10 min. The final oxide product after the oxidation enthalpy measurement was reddish brown and magnetic and was a Fe ₂O ₃ (Haematite) by using the X-ray diffraction pattern. The oxidation enthalpy of Fe ₂O ₃ was estimated to be -185 kcal/mole, which was close to the bulk value.
