Synthesis of magnetite nanoparticles in an ethanol-water Solvent

説明

The effect of ethanol on the formation of magnetite (Fe3O4) was stsudied. Magnetite nanoparticles were synthesized from an Fe(OH)2 suspension (green rust) by oxidation with oxygen dissolved in an ethanol-water solution. There were no Fe3O4 cubic particles instead of needle-like crystal obtained when the pH value was up to 14.2 in 50% ethanol-water solution. The particle size was ~20nm as revealed by TEM photograph. The decrease of ethanol ratio in ethanol-water solution caused the increase of magnetite particle size. It was found that the formation of magnetite was slower in the high ethanol ratio solution.
