Increasing the pH of the pillaring solution by addition of NaOH increases the thermal stability of Zr pillared clays. The improvement may be directly correlated to the amount of ZrO2 and to the density of the pillars. The strong interaction between the pillars and the clays promotes high acidity of this microporous solid.
