Abstract: The storage stability of SO42-/ZrO2 solid superacid in different environments was studied.The samples kept in moist atomosphere lost their superacidity and catalytic activity for butane isomerization within 30 days.The results of TGand IRspectroscopy show that reheating the moistened samples results in a decrease in surface sulfur content,leading to the deterioration of the superacid.The ways to avoid such a disadvantage were suggested.
