AbstractSilica-supported iron oxide nanoparticles are prepared by precipitation within the pores of amine-functionalized SBA-15 silica. The loading of the iron oxide possible by this method is at least 11 wt%. STEM and TEM images show that the supported particles have a uniform diameter (average ∼ 4.0 nm) and are well dispersed. The supported iron oxide nanoparticles are amorphous after calcination at 300°C and, consistent with their nanoscale dimensions, are superparamagnetic at room temperature.

Iron oxide nanoparticles were synthesis by reverse micelle method. X-ray diffraction technique and vibration sample magnetometer were applied to characterize the produced samples at different conditions and parameters for synthesis route. There is no significant difference between samples prepared at 5°C and room temperature except a better crystalline at room temperature. The molar ratio of water to surfactant (w parameter) and concentration of the salt solution on size and magnetic properties of nanoparticles have been investigated. Increasing w leads to producing particles with larger size i.e. for w=16.83, 11.22, and 5.6, particles size are 15.22, 11.66 and 10.5 nm, respectively. The size of nanoparticles are in the range of 9 to 20 nanometers
