Title: Thermochemical Insights into Stability and Hydration of Ion-Exchanged Zeolite ZK-5 (KFI Framework)

Abstract

Extra-framework cations not only have a great impact on the structure of zeolites but also affect energetics and absorption of guest molecules. To investigate the stability and hydration of ion-exchanged zeolite ZK-5, high-temperature oxide melt solution calorimetry and direct water absorption calorimetry were used to reveal the influence of ion exchange on formation enthalpies and hydration processes. Formation enthalpies from oxides suggest that exchanging K⁺ and Cs⁺ with protons leads to destabilization of H-ZK-5, which is accompanied by the transition to an amorphous phase at high temperature. Water absorption and corresponding enthalpies are also affected by charge-compensating cations, for example, Na⁺ ions in Na-ZK-5 promote the confinement of water molecules and generate higher water content and more exothermic absorption enthalpies. It is found that average ionic potentials are insufficient to explain formation enthalpies at different hydration levels, particularly for H-ZK-5 with complex cation forms. Instead, formation enthalpies from oxides generally become less exothermic as the distortion of the zeolite framework increases when replacing cations or absorbing/desorbing water molecules. Furthermore, this thermochemical study demonstrates the critical role of extra-framework cations and documents the complexity of ion exchange effects in zeolites with complicated topology and cation distribution.

Chabazite: Energetics of hydration, enthalpy of formation, and effect of cations on stability

Journal Article Shim, S H ; Navrotsky, A ; Gaffney, T R ; ... - American Mineralogist

The stability of synthetic cation-exchanged zeolites having the chabazite framework (CHA) and their cation-water interaction were studied using high-temperature reaction calorimetry. Four cations (K, Na, Li, and Ca) were exchanged into CHA. The enthalpies of formation were determined for all samples, and the partial molar enthalpy of hydration was measured by varying the water content of one Ca-CHA. The enthalpy of formation depends strongly on the exchanged cation, becoming more exothermic in the order Ca, Li, Na, K. The integral hydration enthalpy does not depend strongly on the nature of the cation, but becomes slightly less exothermic with increasing aluminummore »« less

Journal Article Le, So-Nhu ; Navrotsky, Alexandra - Journal of Solid State Chemistry

Differential scanning calorimetry and high temperature oxide melt solution calorimetry were used to study the enthalpy of the {alpha}-{beta} phase transformation of NaZnPO{sub 4} and enthalpies of formation of {alpha}-NaZnPO{sub 4}, NaH(ZnPO{sub 4}){sub 2}, NaZnPO{sub 4}.H{sub 2}O, and NaCo{sub x}Zn{sub 1-x}PO{sub 4}.4/3 H{sub 2}O (x=0, 0.1, 0.2, 0.3).

Energetics of alkali and alkaline earth ion-exchanged zeolite A

Journal Article Sun, Hui ; Wu, Di ; Liu, Kefeng ; ... - Journal of Physical Chemistry. C

Alkali and alkaline earth ion-exchanged zeolite A samples were synthesized in aqueous exchange media. They were thoroughly studied by powder X-ray diffraction (XRD), electron microprobe (EMPA), thermogravimetric analysis and differential scanning calorimetry (TG-DSC), and high temperature oxide melt solution calorimetry. The hydration energetics and enthalpies of formation of these zeolite A materials from constituent oxides were determined. Specifically, the hydration level of zeolite A has a linear dependence on the average ionic potential (Z/r) of the cation, from 0.894 (Rb-A) to 1.317 per TO₂ (Mg-A). The formation enthalpies from oxides (25 °C) range from –93.71 ± 1.77 (K-A) to –48.02more »« less

Thermochemical data for merlinoite: 1. Low-temperature heat capacities, entropies, and enthalpies of formation at 298. 15 K of six synthetic samples having various Si/Al and Na/(Na + K) ratios

The heat capacities, C{sub P}, and heats of solution, {Delta}H{sub soln}, of six synthetic merlinoite samples having various Si/Al and Na/(Na + K) ratios were measured by low-temperature, adiabatic calorimetry and hydrofluoric acid solution calorimetry, respectively.

On the Structure-Property Relationships of Cation-Exchanged ZK-5 Zeolites for CO ₂ Adsorption

Journal Article Pham, Trong D. ; Hudson, Matthew R. ; Brown, Craig M. ; ... - ChemSusChem

The CO₂ adsorption properties of cation-exchanged Li-, Na-, K-, and Mg-ZK-5 zeolites were correlated to the molecular structures determined by Rietveld refinements of synchrotron powder X-ray diffraction patterns. Li-, K-, and Na-ZK-5 all exhibited high isosteric heats of adsorption (Qst) at low CO₂ coverage, with Na-ZK-5 having the highest Qst (ca. 49 kJ mol^-1). Mg2+ was located at the center of the zeolite hexagonal prism with the cation inaccessible to CO₂, leading to a much lower Qst (ca. 30 kJ mol-1) and lower overall uptake capacity. Multiple CO₂ adsorption sites were identified at a given CO₂ loading amount for allmore »« less
