Abstract :
Nanocomposite iron oxide-SiO2 materials were prepared by sol-gel method starting with two type of precursors, tetraethoxysilane (TEOS) and methyltriethoxysilane (MTEOS), as SiO2 source. The iron oxides was generated during the sol-gel process from a soluble iron salt. The initial gels and the thermally treated samples were characterized by EPR measurements, transmission electron microscopy (TEM) and BET surface area methods
