Abstract. The intercalation process of α-zirconium phosphate (α-ZrP) was investigated by using two α-ZrP samples with different levels of crystallinity and two structurally different intercalating molecules, i.e., linear hexylamine and non-planar cyclohexylamine. The results show that the intercalation energy barrier, which is affected by both host α-ZrP and guest intercalating molecule…
