- Abstract
- Zirconium phosphonates layered structure (ZPLS) materials with various organic pendant groups have been synthesized. Their physical properties were investigated by means of SEM, BET, XRD, TGA/DTA and FT-IR. These properties, crystallinity in particular, depended strongly on preparation conditions and the nature of the pendant. In general, samples with a sulfonic acid pendant were not as crystalline as the carboxylic acid analogs. Crystalline samples exhibited a plate-like morphology as commonly observed for layered structure materials. Interlayer spacing of these materials was roughly proportional to the size of the pendant. In comparison with a conventional cation exchanged resin (Amberlyst 15), the layered structures with a sulfonic acid pendant showed similar IR characteristics, but much better thermal stability.
