摘要：
The structure of the Pd-Zn/alpha-Al2O3 catalyst, which was prepared by a joint impregnation method, was studied. According to XRD analysis data, supported intermetallic Pd-Zn particles were formed in a temperature range of 200-600A degrees C. At 600A degrees C, the crystal lattice of substitutional solid solution based on Pd (FCC) was finally rearranged into the tetragonal lattice of Pd-Zn. A shift of the Pd3d(5/2) line in the XPS spectrum indicated the formation of the Pd-Zn intermetallic compound.
