Iron oxide nanoparticles have wide application in electronics, medicine, energy, environmental remedy, and biotechnology. Currently, organic solvents are employed to synthesize iron oxide nanoparticles with precisely controlled size and tunable magnetic properties. For large scale produce in industry, the synthetic method will lead to both high environmental concern and cost. There is unmet need to reduce the massive use of reaction solvents. In this study, a green one-pot reaction route has been developed for the preparation of iron oxide nanoparticles. The iron oxide nanoparticles are synthesized by thermal decomposition of iron (III) acetylacetonate (Fe(acac)3) in diethylene glycol (DEG). The reuse of the DEG solvent in the synthesis of Fe3O4 nanocrystals was demonstrated, and more than 90% of the solvent can be recycled. Furthermore, reuse of the recovered solvent to synthesize Fe3O4 nanoparticles does not affect their physicochemical properties. The formation of monodisperse particles was evident by using TEM (Transmission electron microscopy), XRD (X-ray diffraction), SEM (Scanning Electron Microscopy) with EDX (Energy Dispersive X-Ray Analysis), and FTIR (Fourier transform infrared spectroscopy). The data illustrated that the nanoparticle size increases with the addition of a new precursor. In conclusion, this research provides a green and economical strategy which is very promising in Fe3O4 synthesis.
