CTAB-assisted of Fe2O3/CeO2 nanosized prepared by coprecipitation method

Recently, cerium oxide (CeO2) nanoparticles have been widely used in engineering andmedical sciences due to the diversity of their applications. Fe-Ce nanoparticles were synthesized bysimple co-precipitation method via iron nitrate (Fe(NO3)3.9H2O) and cerium nitrate (Ce(NO3)3.6H2O) asprecursor in the presence of cetyltrimethylammonium bromide (CTAB) surfactant. The samples werecharacterized by high resolution transmission electron microscopy (HRTEM), field effect scanningelectron microscopy (FESEM), X-ray diffraction (XRD), vibration sampling magnetometer (VSM), andFourier transform infrared spectroscopy (FTIR) in different temperature. The XRD results showed thatFe-doped CeO2 was single-phased with a cubic structure. The particle size of as-prepared sampleswas around 45 nm and for annealed one was around 32 nm in diameter at 500 °C for 3 hours. TheTEM studies showed the squared-like shaped nanosized particles with good distribution particle. Thesharp peaks in FTIR spectrum determined the element of Fe-Ce nanoparticles. The result of magneticmeasurements showed coercive field and saturation magnetism around 1632 G and 0.055 emu/g,respectively for as-prepared samples.
