Properties of iron oxides inserted into SBA-15 mesoporous silica

Abstract The present work is dedicated to the research of nanocomposites based on particles of different iron oxides developed inside mesoporous SBA-15 silica soaked in iron(III) oxalate aqueous solution by thermal treatment under various conditions (temperature, environment). The effect of the conditions applied on properties and phase composition of the samples has been studied. All the samples obtained are superparamagnetic with roughly uniform iron distribution.
