Реферат: Three-way catalysts are well known systems used for neutralization of gasoline automotive emissions. As a rule they contain palladium and rhodium as active components providing the conversion of pollutants via a number of oxidation and reduction reactions. The catalysts with atomically dispersed or sub-nanometer sized ionic clusters of precious metals have been recently shown to have the highest activity in these reactions. In our previous study, we have observed that alumina donor sites play defining role in stabilization of atomically dispersed forms of supported Pd. The present study is focused on the activity and stability of bimetallic Pd–Rh catalysts obtained from heterometallic complexes and supported on gamma-Al2O3. The total precious metal loading in the synthesized samples was as low as 0.2 wt. % that complicated the use of the most of conventional physical and chemical methods of characterization
