Data for Microwave-Assisted Rapid Synthesis of Metallic Iron Nanoparticles from Triiron Dodecacarbonyl Ehsan Ezzatpour Ghadim (25035280) Festus Slade (25019893) Yisong Han (1411153) Rafael C. Marchi (12703078) Joanna F. Collingwood (1311405) Peter J. Sadler (24951436) Migrated from ePrints Zero-valent iron (Fe(0)) nanoparticles have a wide range of applications, including catalysis, energy storage and a potential role in human brain neurochemistry. This study shows that [Fe3(CO)12] can be dissolved in N,N-dimethylformamide (DMF). It is used to produce Fe(0) at 368 K (243 W) in 30 s with a microwave reactor. The use of microwave yielded well-dispersed, pure Fe(0) nanoparticles, and the samples yielded between 97.3 and 98.5 %. The effect of time on controlling the size of particles is studied and characterized using scanning electron microscopy (SEM). Annular dark-field scanning transmission electron microscopy (ADF-STEM) shows the average size of nanoparticles in 30 s and 368 K to be 25.7 nm. The sizes of the particles vary in electron microscopy (EM) between 20 and 40 nm. The powder X-ray diffraction (PXRD) of the Fe (0) profile indicates the pure phase, face-centred cubic (FCC) structure with Fm3 ̅m space group and γ-Fe phase. Regarding the time changes between 5 min and 30 seconds, the unit cell parameters vary between 3.53911 (0.00018) and 3.53144 (0.00009) Å. This facile procedure significantly improves the safety profile and reaction control to provide a practical method for synthesizing pure Fe(0) nanoparticles.<br><br>Powder X-ray diffraction, Fourier transform IR, UV-Vis spectroscopy and high-resolution transmission microscopy data on metallic iron nanoparticles from triiron dodecacarbonyl 2025-11-07T00:00:00Z Dataset Dataset 10.82444/warw.33907003.v1 https://figshare.com/articles/dataset/Data_for_Microwave-Assisted_Rapid_Synthesis_of_Metallic_Iron_Nanoparticles_from_Triiron_Dodecacarbonyl/33907003 CC BY 4.0
