Silica-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.
