Direct Conversion from Oleylamine-coordinated Iron Oxalate Powder to Colloidal Magnetite Nanoparticle via Simple Thermal Treatment
Colloidal magnetite (Fe3O4) nanoparticles were synthesized via thermal decomposition of oleylamine-coordinated iron oxalate powder, which gradually becomes liquid at high temperature without the need of any chemical additions. Fe3O4 nanoparticles with an average diameter of 10.2nm were synthesized in the liquid at 300 degrees C for 60 mM. The synthesized Fe3O4 nanoparticles were well dispersed in toluene.
