In this work, a facile synthetic process is reported for the large‐scale synthesis of Fe 3 O 4 nanocrystals. Thermal decomposition of Fe(acac) 3 (100 g) in 1‐hexadecanol produced Fe 3 O 4 nanocrystals with well‐controlled sizes and morphologies. The nanocrystals were spherically shaped with average diameters of 7.8 ± 0.6, 6.5 ± 0.4, and 5.9 ± 0.2 nm when prepared at 300°C, 270°C, and 250°C, respectively. Mechanisms of crystal formation were elucidated on the basis of gas chromatography‐mass spectroscopy analysis, enabling the large‐scale preparation of Fe 3 O 4 nanocrystals. To provide an environmentally benign route, Fe 3 O 4 nanocrystals were prepared with recycled solvent which was recovered from the initial experiment. The resulting porous Fe 3 O 4 nanocrystals had larger average sizes than those of the initial nanocrystals. Structural characterization was performed using transmission electron microscopy and powder X‐ray diffraction.
