Abstract: Crystalline phase is the key factor for catalyst activity. The zirconium modified PCs/γ-Al2O3 samples were prepared through a simple step incipient-wetness impregnation method. The raw materials and samples were characterized by thermogravimetric-differential analysis (TG-DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), temperature-programmed desorption of ammonia and carbon dioxide (NH3-and CO2-TPD). The effects of calcination temperature and zirconium content on structure, chemical transformation, and acidity-basicity were investigated. Calcination temperature exhibited the major effect on the crystalline phase of samples. The new phase of Al0.1Zr0.9O1.95 was exhibited which was above 650℃. In addition, zirconium content was influenced by the acidic and basic properties of the surface. The acidity and basicity of the ZrPCs/γ-Al2O3 sample increased with the increasing of zirconium content.
