Behavior of transition metals in the structuring of nanostructures.

The mixed oxides of SiO2–TiO2, MoO3–SiO2–TiO2, CoO–SiO2–TiO2 and MoO3–CoO–SiO2–TiO2 are prepared from a stable homogeneous mixture based on transition metals. During the preparation, it is necessary to know the duration of the stability of this solution, to control its stability, use the Zetasizer. The sol-gel process is one of the most widely used synthetic methods. This leads to the formation of homogeneous products. In present study; the structure, composition, particle size, morphology and porosity of the particles are obtained. The nanostructured mixed oxides has been characterized by physico-chemical analysis methods, including Acidity, Zeta potential, FTIR, BET, X-ray diffraction and TEM. [ABSTRACT FROM AUTHOR]
