Influence of Thermal Treatment on the Phase Compositions and Elemental Distributions of Co - Containing Catalysts
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 10
Abstract
The great importance of nano-structured materials has been motivating the search for new synthesis methods for these types of materials. This paper is primarily focused on the characterization of cobalt nanoscale oxides synthesized by a method based on reaction of fine-dispersed Al flakes with dichloroethane in paraffin medium in the presence of cobalt chloride at different calcined temperatures forming catalytic complexes. This chemical-based synthesis route is briefly described, and the feasibility of obtaining such oxides. Characterization was done by X-ray fluorescence microscopy (XRFM), X-ray diffraction (XRD), which revealed, respectively, the presence of oxides and their nanoscale structures, including the elemental distribution and mass thickness of the these elements over the layers . In addition, some materials presented crystalline phases in their inner structure with different size under different targeted temperature.
