1A simple strategy to synthesize and characterization of zirconium modified PCs/γ–Al_2O_3显示文摘Crystalline phase is the key factor for catalyst activity. The zirconium modified PCs/γ-Al_2O_3 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(NH_3-and CO_2-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 Al0.1Zr_(0.9)O_(1.95) 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 Zr PCs/γ-Al_2O_3 sample increased with the increasing of zirconium content.Chidchon Sararuk Dan Yang Guoliang Zhang Chunshan Li Suojiang Zhang 2018Chinese Journal of Chemical Engineering2018,26,5:1
