摘要：
Basicity of ZrO2 is enhanced by KF modification due to the reaction of KF with ZrO2 surface: KF + ZrO2 --> K2ZrF6 + KOH. After pretreated above 673K, KF/ZrO2 catalyst exhibited higher activity for 1-butene isomerization at 273K than ZrO2. The amount of basic sites strongly adsorbing CO2 in the form of bicarbonate was also increased.
