| Description |
Composites which contain iron oxide nanoparticles and unmodified or aminated silica were synthesised by in situ precipitation of ferrous salts in chitozan or glucose solution. Nanocomposites based on oxidized or aminated carbon nanotubers were obtained by immobilizing oxide nanoparticles in surface layer during salt precipitation in water dispersion. The metal-containing phase was obtained by the Elmore reaction using different ratios of ferrous ammonium sulfate hexahydrate (FeSO4∙(NH4)2SO4∙6H2O) and ferric chloride hexahydrate (FeCl3∙6H2O). The composites obtained were characterized using FTIR spectroscopy. In addition for selected samples XRD, DSC, and specific surface area measurements were carry out. The analysis results indicate that in situ co-precipitation of iron oxide precursors in chitosan or glucose allows producing Fe3O4 particles with the average size ca. 5-7 nm. The presence of silica leads to particles size decrease which can be controlled, along with iron oxide particles location, by changing the silica surface functional ity. Characteristics and location of iron oxide nanoparticles in nanotubers modified layer are strongly depended from nature of the groups attached to surface. |
