Abstract:
The standardless stoichiographic differential dissolution (DD) method is used for phase analysis of superfine multicomponent oxide precursors of Fe-Co MWCNT synthesis catalysts obtained by the Pechini method. The analysis identifies the individual phases in the studied samples of Fe2Co/Al2O3, Fe2Co/MgO, and Fe2Co/CaCO3 and determines their stoichiometric composition and quantitative content. It is found that the samples are a complex mixture of superfine oxide phases the composition of which corresponds to a spinel structure and may simultaneously include both active (Fe and Co) and carrier elements (Al and Mg) to form solid solutions. It is only the Fe2Co/CaCO3 samples that contain a carrier-free phase the composition of which corresponds to a spinel structure.
