摘要：

The structure of the Pd–Zn/α-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 200–600°C. At 600°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 Pd3d5/2 line in the XPS spectrum indicated the formation of the Pd–Zn intermetallic compound.
