3D Composites Based On Opal Matrix and Heterometallic Nanoparticles

摘要：

　　3D nanocomposites based on ordered o pal matrices (OM) and metallic nanopartides were pre pared via reduction of salts or oxides of metals from the iron subgroup (Ni, Co, Fe), either as individual salts or their binary or triple mixtures, using supercritical iso propanol.Effect of the precursor salt nature (nitrate or chloride) on composition of respective product has been studied.For the first time, nanopartides comprised of metallic iron or its intermetallides with ordered struc tures (Ni3Fe, NiFe, CoFe) were detected in composites prepared from Fe, Ni-Fe, or Co-Fe nitrates using the method described.Also, magnetic properties of the com posites prepared have been studied.
