abstract

• Magnetite nanostructures coated with carbon layers have been synthesized using spray pyrolysis of ferrocene dissolved in mixtures of alcohol and de-ionized (DI) water. It was found that the type of alcohol (methanol, ethanol or 2-propanol) used in the synthesis process is an important parameter of the thickness and type of carbon (graphitic or amorphous carbon) layers surrounding the iron oxide nanoflakes. The magnetite hexagonal nanocomposites synthesized using methanol showed lower thermal stability than those obtained by using 2-propanol or ethanol, in which the quantity of carbon layers surrounding the magnetite nanostructures is large. The magnetic properties at room temperature of the three types of samples were very similar and the differences between them can be attributed to different carbon fractions and the type of carbon layer covering the magnetite nanostructures. © 2016 IOP Publishing Ltd.
