| Abstract The solvated metal atom impregnation(SMAI)method was employed to Prepare three kind of Pd-Cu/C bimetallic catalysts with diffrent Pd/Cu ratios.The results of XRD and TEM measuments showed that Pd-Cu alloy was formed and the particle size of the alloy was very small,with average diameter<5.0nm.XPS and Auger spectra indicated that both Pd and Cu were in zero-valent state, As Cu contents increased,the catalytical activities of the catalysts in the hydrogenation of mesityl oxide increased, while the selectivities for 4-methyl-2-pentanone were essentially unchanged. |
