Poster summary

In the present work, alumina-supported trimetallic catalysts containing Rh, Ru and Pd in their composition were synthesized and studied in comparison with bimetallic Pd-Rh/Al2O3 reference sample. The starting compounds were solid solutions of double complex salts of corresponding metals synthesized by known procedures. The single phase of the synthesized complexes was confirmed by X-ray diffraction analysis. The synchronous thermal analysis method was applied to investigate the process of thermolysis of synthesized DCS in both reducing and oxidizing atmospheres. It has been found that in the process of thermal decomposition, it is possible to obtain alloy nanoscale trimetallic (Rh-Ru-Pd) particles of a given composition anchored on the surface of an oxide support. The activity and stability of the catalyst compositions obtained were examined in CO oxidation reaction carried out under prompt thermal aging conditions.
