Abstract

Abstract: In this study, a simple fabrication of carbon composited Fe3 O4 nanoparticles was carried out under reflux condition using glucose as a carbon precursor. The carbon composited Fe3 O4 nanoparticles having a core-shell structure were synthesized in a low-temperature and low-pressure atmosphere instead of in an autoclave. Simple carbonization without inert gas and extra heating was complemented by adding sulfuric acid, which has an important role as a carbonization catalyst. In addition, sulfuric acid also acted as the controller of such surface properties as surface area by an etching effect. The prepared nanoparticles have uniform and continuous carbon layers, which have several functions, such as stable dispersibility and an increase of electron conductivity. carbon composited Fe3 O4 nanoparticles were investigated with zeta-potential, particle size distribution, Fourier transform infrared, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and a vibrating sample magnetometer. The results provide clear evidence that carbon-coated Fe3 O4 nanoparticles are applicable in electrochemical industrial fields.
