Abstract

The synthesis of very fine maghemite-based nanoparticles (around 4 nm in size) using one step pulsed laser oxidative pyrolysis has been reported. In the synthesis of the first sample we used iron pentacarbonyl as precursor, air as oxydant and ethylene as laser energy transfer agent. The second sample was synthesized in similar conditions with supplementary introduction of 1,3-diaminopropane vapors in order to obtain a nitrogen-based functionalized nanoparticles surface. The samples were characterized by XRD, EDX, FTIR, TEM and SAED techniques which confirm the complex structure of the resulted nanoparticles with iron oxide cores surrounded by more disordered carbonaceous shells containing oxygenated and, for the second sample, nitrogenated functional groups..
