Abstract

The management of matter at the nanoscale has meant the development of a diversity of methodologies which allow obtaining nanostructures with potential properties of high applicability, but at the same time it is accompanied by highly polluting processes due to the use of inorganic chemical reagents. This research presents a sustainable method for the synthesis of iron oxide nanoparticles (FeO NP) using the metabolic compounds of the aqueous extract of Eucalyptus globulus as organic reductant, which have been widely characterized. The results suggest the excellent role of the organic extract of E. globulus as a reducer and stabilizer, which in turn is confirmed by the presence of the surface plasmon resonance peak at 390 nm, typical of the formation of FeO NP, likewise, the result of structural characterization shows the presence of the magnetite phase, it also presents a spherical morphology with an average size of 3 nm, the elemental analysis by EDS reinforces the presence of iron in the nanostructured material, in addition to a Z potential of 13.58 mV. The magnetization analysis shows a superparamagnetic behavior that is a function of temperature with values of 12.5 emu/g (5 K) and 8.2 emu/g (300 K).
