This dissertation is a thermodynamic study of zeolites and zeolite-like materials. The zeolite materials include alkali and alkaline earth cation (Li+, Na+, K+, Rb+, Cs+, Ca2+, Sr2+ and Pb2+) exchanged natrolite, transition metal cation (Mn2+, Co2+, Cu2+, Zn2+) exchanged zeolite A and zeolite Y, ITQ-33 (large pore Ge-zeolite) and zeolite beta polymorph C (BEC). The zeolite-like materials are hollandites substituted by Rb+, Cs+ and Sr2+. Zeolites form a large group of aluminosilicate porous materials. They continue receiving interest in terms of crystal structure, Si/Al ratio, cation effects, ion exchange, hydration, and technological applications, such as heterogeneous catalysis and heavy metal disposal. In this dissertation, thermodynamic properties of zeolites with different topology, pore size and especially various exchanged cations are investigated. The first part is about natrolite, which is a small pore (2.6 Å) zeolite mineral. It has been applied in industrial catalysis and waste water treatment. To answer several fundamental questions about Al/(Al+Si) ratio effects, abnormal rehydration behavior of K-NAT, Rb-NAT and Cs-NAT and cation effects, and also to explore the thermal behavior of natrolite and the factors that affect its persistence, a series of synthetic natrolites with different extra-framework cations (Li, Na, K, Rb, Cs, Ca, Sr and Pb) were investigated by differential scanning calorimetry and high temperature oxide melt solution calorimetry. The formation enthalpies from constituent oxides obtained from high temperature solution calorimetry align well with those observed previously for other zeolites. Their formation enthalpies become less exothermic with increasing ionic potential (Z/r) of the cations. The hydration enthalpies obtained from differential scanning calorimetry indicate that water binding becomes weaker with increasing cation size. A formation enthalpy model for hydrous zeolites similar to that for anhydrous zeolites was developed. The further analysis of results indicates cation effects are more important than hydration effects on stability. Large pore zeolites such as the ITQ series have attracted much attention for their accommodation of larger guest molecules and promising potential in catalysis. The synthesis of large pore zeolites can be realized by using several strategies, such as large and rigid organic structure directing agents (OSDAs); concentrated gels and fluoride media, especially with Ge substitution. To explore their application in industry, thermochemical study of their stability is important. In chapter 3, energetics of large pore Ge-zeolite ITQ-33 and pure silica zeolite beta polymorph C (BEC) with two types of OSDAs were studied. The enthalpies of formation from phases with the quartz structure (SiO2 and GeO2) have been determined. The BECs made with two different structure directing agents (SDA) show energetic difference of 4 kJ/mol due to structure defects. The enthalpy of formation of ITQ-33 (Ge/(Ge+Si) = 0.3) supports the energetic trends seen in other Ge-zeolites, namely the enthalpy of formation becomes more endothermic as the content of double four rings (D4R) increases. Also the energetic trend of porous materials versus molar volume is extended by the present data, with a diminishing destabilization for very open structures. Zeolites have good ion exchange capacity which offers a large area of study on various cations effects in different frameworks. An area of big interest is transition metal cation decorated zeolites for the double catalytic properties of transition metal cations and zeolite frameworks, and also the highly dispersed metal sites. To study the unique cation effect and energetic properties, in chapter 4, Mn, Co, Cu, Zn- exchanged zeolite A and Y were prepared and studied by thermogravimetry - differential scanning calorimetry (TG-DSC) and high temperature oxide melt solution calorimetry. All these transition metal zeolites could be synthesized by aqueous solution exchange methods. The thermodynamic results revealed an unusual trend of cation effects compared to alkali and alkaline earth containing zeolites. The formation enthalpies of Mn and Zn zeolites A and Y are less endothermic than those of Co and Cu-zeolites A and Y. Their relative stabilities are consistent with metal-oxygen bond lengths, and could be explained by the crystal field effects of transition metal ions. The enthalpies of exchange of transition metals for sodium in zeolites A and Y are strongly unfavorable. In the last part, Chapter 5, an aluminotitanate ceramic material, hollandite, that has a framework structure analogous to a zeolite is studied in terms of synthesis, structural characterization and energetics. With good tolerance for cation substitution, hollandite is a potential host to immobilize radioactive elements, particularly cesium and strontium fission products. In this study, Rb+, Cs+ and Sr2+ containing hollandite was synthesized using a sol-gel method and characterized by synchrotron XRD. Their enthalpies of formation were explored using high temperature oxide melt solution calorimetry. Their stabilities are similar but decrease slightly from Cs- to Rb- to Sr-hollandite.

Zeolites occur in nature and have been known for almost 250 years as alumino silicate minerals. Examples are clinoptilolite, mordenite, offretite, ferrierite, erionite and chabazite. Today, most of these and many other zeolites are of great interest in heterogeneous catalysis, yet their naturally occurring forms are of limited value as catalysts because nature has not optimized their properties for catalytic applications and the naturally occurring zeolites almost always contain undesired impurity phases. It was only with the advent of synthetic zeolites in the period from about 1948 to 1959 (thanks to the pioneering work of R. M. Barrer and R. M. Milton) that this class of porous materials began to playa role in catalysis. A landmark event was the introduction of synthetic faujasites (zeolite X at first, zeolite Y slightly later) as catalysts in fluid catalytic cracking (FCC) of heavy petroleum distillates in 1962, one of the most important chemical processes with a worldwide capacity of the order of 500 million t/a. Compared to the previously used amorphous silica-alumina catalysts, the zeolites were not only orders of magnitude more active, which enabled drastic process engineering improvements to be made, but they also brought about a significant increase in the yield of the target product, viz. motor gasoline. With the huge FCC capacity worldwide, the added value of this yield enhancement is of the order of 10 billion US $ per year.

It is designed as a reference work for zeolite chemists and materials scientists, but it also serves as a tool to interpret structural similarities and to derive new structures from known topologies. Zeolites and zeolite-like materials became important because of their ion exchange capacities and their outstanding catalytic properties. Millions of tons of zeolites have been produced in the past years for the oil refining industry alone and, in even greater quantities, as ion-exchanging softening agents for detergents. Numerous other applications, e.g., in environmental protection, farming, gas separation, medicine, and pharmacy, are known, making zeolites almost a necessity for daily life. Consequently, there are many research activities dealing with zeolite properties and characterization.

The Zeolites and Mesporous Materials at the Dawn of the 21st Century Proceedings are the expression of the oral and poster communications which where presented during the 13th International Zeolite Conference (IZC). They are subdivided into 32 thematic sessions starting from the genesis of materials to their applications through their characterisation. The paper volume contains the full texts of the 5 plenary and 6 keynote lectures and informative summaries of 150 oral and 540 poster presentations. These contributions have been selected among the 903 submissions received from a total of 57 countries! In order to gather all the communications in a handy document, the full texts of oral and poster presentations are available in CD-ROM. Besides the fields of zeolite science always represented at IZC (synthesis, characterisation, catalysis, etc¿), some subjects strengthened their position (mesoporous materials, theory and modelling), new areas emerge (advanced materials, environmental and life sciences) and older ones regain interest (natural zeolites). The understanding and development of the unique properties of porous materials relies on a unique blend of multidisciplinary knowledge: material science, with the implication of organic and colloid chemistry, to prepare micro- and mesoporous materials, surface and adsorption science sustained by theory and modelling to understand the peculiar behaviour of molecules in confined systems, special branches of catalysis, physics, chemical engineering and life science to design novel applications. The gathering of these elements is at the basis of a fruitful and evolutionary zeolite science, as it is hopefully reflected by these proceedings.

1. Introduction. There is much interest in the general subject of porous inorganic materials with respect to their use as sorbents or catalysts. Such inorganic solids may be microporous, mesoporous or macroporous according to the sizes of the pores within the solid. Often there is a range of pore sizes within any given solid and so there is special interest in the synthesis, characterisation and application of porous inorganic solids with well defined pores. Pores of diameter larger than 50 nm are generally termed macropores. Those with diameters of less than 2 nm are micropores and pores of intermediate size are called mesopores. Solids, which contain only mesopores, are correctly called mesoporous but very often there is a combination of different types of porosities within one given solid. The synthesis, characterisation and application of microporous solids is much more advanced than is the case with mesoporous substances. Moreover, the synthesis of crystalline mesoporous materials is one clear goal for the future but which has not been attained so far. Consequently, it is of interest to examine the current state of our knowledge of microporous materials and to examine how this may apply to mesoporous materials. Both catalytic and sorption processes could benefit from studies of mesoporous solids because the mesopores could permit diffusion of larger reactants or products than is the case in microporous materials. 2.
