Synthesis and characterization of magnetite (Fe3O4) nanoparticles with different level of aniline dimer-COOH by co precipitation method

The morphologies of the magnetite (Fe3O4) nanoparticles with certain level of aniline dimer-COOH were prepared via assisted co-precipitation method. The Fe3O4 nanoparticles morphologies are observed by Field Emission Scanning Electron Microscope (FESEM) and the result shows that, the Fe3O4 nanoparticles prepared with aniline dimer-COOH is agglomerated and more spherical in shape and size. The phase analysis of the Fe3O4 nanoparticles was perform by X-ray Diffraction spectra (XRD), the result indicates that, the particles prepared with littlie amount of aniline dimer-COOH have more peaks compare to the uncapped Fe3O4 nanoparticles. However, the molecular structure and functional group of Fe3O4 nanoparticles were studied using Fourier Transform Infrared Spectra (FTIR) and the result proven the appearance Fe-O band of the molecules.The morphologies of the magnetite (Fe3O4) nanoparticles with certain level of aniline dimer-COOH were prepared via assisted co-precipitation method.
