Abstract Scope |
Zeolites, layered double hydroxides (LDHs) and clays are naturally occurring mineral hosts, which accommodate guest species, such as water, carbon dioxide, ions and organic species in natural environments and industry applications. Here, I present our study on the thermodynamic stability and energetics of guest – host interactions within transition metal ion-exchanged mordenite (TM-MOR), nickel-aluminum bimetallic LDH and a series of clays using various calorimetric techniques, including thermogravimetric analysis – differential scanning calorimetry – mass spectroscopy (TG-DSC-MS) analysis, water adsorption calorimetry and near-room temperature acid solution drop solution calorimetry. Coupled with in situ FTIR and in situ XRD analyses, our results suggest complex interplays among compositional, structural and interfacial factors, which are governed by the overall energetic state of each system, and determine the properties of 2D and 3D mineral hosts in both natural environment and industrial applications. |
