Preparation and Decomposition Study of 2, 3-Pyridinedicarboxylate Intercalated Layered Double Hydroxides

Abstract

Supramolecular 2,3-pyridinedicarboxylate intercalated NiAl-layered double hydroxides (2,3-pyridinedicarboxylate-NiAl-LDHs) has been prepared by direct coprecipitation method. The solid product was found to have a greatly expanded LDH structure. Possible orientation of 2,3-pyridinedicarboxylate between the interlayer region has been proposed. Furthermore, its thermal decomposition process was studied by the use of TG-MS and in situ HT-XRD.
