About Si – O – Fe bounds in iron oxide – silica nanocomposites
Анотація
The conditions have been studded for Si – O – Fе bonds forming and peculiar structure of iron oxides in iron oxide – silica systems by means of IR-spectroscopy, XPS and XRD. Thermal stabilities of g-Fe2O3 and Fe3O4 was found to increase in the presence of amorphous silica what could be related to appearance of Si – O – Fе bonds in nanocompounds.
