Abstract
Copper–palladium bimetallic catalysts supported on mixed oxides (MgO)0.75(Al2O3)0.25 (MgAlO) were prepared with two step impregnation (TSI) and co-impregnation (CI). These materials were studied to determine the effect of the support on the activity and stability in the Suzuki–Miyaura reaction and on the properties of a catalyst. The catalyst prepared by CI was active and selective during 6 catalytic cycles in Suzuki coupling, whereas the activity of the catalyst prepared with TSI dropped at the sixth use. The kinetics of the reaction was examined along with its scope. The relationship between the basic properties of the support and the catalytic performances were examined too. The importance of the nature of the support was also studied by catalyst characterization methods.
