Abstracts

EN

The properties of Fe-Co catalysts in the reaction of CO₂ hydrogenation were investigated. Samples with high cobalt concentrations have shown higher activity. Morphology of the obtained catalysts was observed by using scanning electron microscopy and the elemental composition of surface of the catalysts was determined by scanning electron microscopy-energy dispersive X-ray method. Energy dispersive X-ray analysis showed that metal distribution is not homogeneous with various metal ratio in selected points of the surface for the Fe-rich less active samples, whereas for the Co-rich samples with higher activity metals are homogeneously distributed, which is possibly connected to the formation of single phase.
