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.
