摘要：A series of crystalline hydrous zirconia supports were prepared by different methods. The preparation method affected the crystallization of the supports and catalytic activity of Pt/WO3-ZrO2 for n-hexane isomerization. The catalysts were characterized by X-ray diffraction, Raman spectroscopy, and NH3 temperature-programmed desorption. The crystallization of hydrous zirconia was affected by the ambience used in the synthesis. Crystalline hydrous zirconia prepared in the absence of oxygen led to a catalyst with high activity, and the case was the opposite when it was prepared in the presence of oxygen.
