摘要

Abstract

Crystalline phase is the key factor for catalyst activity. The zirconium modified PCs/γ-Al

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

-and CO

-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

0.9

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 ZrPCs/γ-Al

sample increased with the increasing of zirconium content.
