| Abstract: | Cobalt and iron nanocomposites have been prepared by in situ reduction of metallic salts in SiO2 gel matrices. The presence of nanosized metal phases has been established chemically as well as by selected area diffraction and transmission electron microstructural analyses. Studies on temperature and time dependent fractional reduction revealed that the reduction kinetics are fast. |
