英文摘要: A series of hydrous zirconia samples were prepared by the hydrothermal method, and the Pt/WO3-ZrO2 catalyst was prepared by impregnation. The effects of hydrothermal temperature of Zr(OH)(4) on the isomerization activity of the catalyst was investigated. The crystalline structure, acidity, and reduction properties of the catalyst were characterized by X-ray diffraction. NH3 temperature-programmed desorption, and H-2 temperature-programmed reduction, respectively. The results indicated that the crystalline structure of hydrous zirconia and the catalyst varied with the hydrothermal temperature, and the increase of hydrothermal temperature reduced the fraction of tetragonal zirconia. Strong acide sites on the catalyst and the isomerization activity increased with the crystallization of Zr(OH)(4). It was proposed that the higher isomerization activity may be related to the existence of large numbers of strong acid sites.
