Effect of experimental parameters on the synthesis of Fe3O4 nanoparticles by ascorbic acid mediated reduction of Fe(acac)3

Abstract

Synthesis of Fe3O4 nanoparticles was carried out by ascorbic acid mediated reduction of Fe(acac)3. In order to achieve control over size, synthesis was carried out at different synthesis conditions. Small (8 nm, 9 nm and 15 nm), medium (22 nm, 29 nm, 33 nm and 42 nm) and large (76 nm, 108 nm) sized Fe3O4 nanoparticles have been synthesized by varying and controlling the experimental conditions. Mechanism for the formation of Fe3O4 nanoparticles is proposed. Our method is observed to yield reproducible results, confirmed by doing the repeated synthesis several times.
