Schematic overview of the reaction pathway leading to magnetite (Fe3O4) nanoparticles (NPs). The mechanism is elucidated using a combination of in situ techniques made possible by the versatile reactor setup. ATR-IR spectroscopy monitors the evolution of organic species throughout the reaction. XAS and PDF analyses reveal the conversion of the initial iron(III) acetyl­acetonate complex to the intermediate ferric acetate complex, followed by the formation of the magnetite phase. PXRD measurements track the emergence of the magnetite crystal structure and NP growth.
