Abstract
Nanocomposites based on nanoparticles of iron oxides formed inside porous matrices were studied. Mesostructured silica material SBA-15 impregnated with an aqueous solution of iron(III) oxalate was heattreated in oxidizing (air) and reducing (Ar + 5% H2) media. The resulting samples exhibited small oxide particle sizes (ca. 5 nm) and sufficiently uniform distribution of iron whose content was ~16 wt %.
