摘要：
pH effect on the preparation of ZrO2/SiO2 catalysts by sol-gel method was studied. Basic and acidic media were used during the gelation of tetraethoxysilane (TEOS) and zirconium acetate. In acid medium the catalysts showed high acidity and high specific surface area up to 805 m2/g, whereas in the basic preparations the opposite effect was observed.
