Zeolite science and technology has been and continues to be an area receiving great attention. Increasing interest in the synthesis and the characterization of zeolite and microporous materials is reflected in the large number of contributions. Other areas gaining recognition include novel materials, adsorption, theory and modeling.

This volume is a collection of 14 plenary lectures and 25 invited and contributed papers which were presented at the International Symposium on Chemistry of Microporous Crystals (CMPC) held at Sophia University in Tokyo, Japan. The symposium was organized by the Japan Association of Zeolite in collaboration with twelve major academic Japanese societies dealing with the chemistry of microporous crystals. The symposium was attended by over 250 researchers from 13 countries.The objective of the symposium was to present new horizons and developments in the chemistry and application of natural and synthetic crystalline materials having microporous structures. At this meeting the following trends were noted: new possibilities for highly selective oxidation of hydrocarbon and synthesis of fine chemicals using modified zeolites and metallosilicates; sophisticated syntheses of some valuable hydrocarbons such as 2,6-dimethylnaphthalene and styrene which could not be obtained successfully by conventional catalysts; detailed mechanism of decomposition and aromatization of paraffinic hydrocarbons on zeolitic catalysts; methanol conversion on zeolite catalysts; syntheses of novel wide pore aluminophosphates and their isomorphously substituted porous crystals; detailed analysis of the state of cations in zeolites and metallosilicates; application to direct decomposition of nitric oxide; dynamic behavior of molecules in zeolite pores; chemistry and reaction performance of clay minerals. This proceedings volume contains thorough reviews and original contributions, each of which includes an extensive list of references. The result is a comprehensive overview of the chemistry of zeolite and zeolite-like crystalline materials and clay minerals, including pillared clays.

Intensive research on zeolites, during the past thirty years, has resulted in a deep understanding of their chemistry and in a true zeolite science, including synthesis, structure, chemical and physical properties, and catalysis. These studies are the basis for the development and growth of several industrial processes applying zeolites for selective sorption, separation, and catalysis. In 1983, a NATO Advanced Study Institute was organized in Alcabideche (portugal) to establish the State-of-the-Art in Zeolite Science and Technology and to contribute to a better understanding of the structural properties of zeolites, the configurational constraints they may exert, and their effects in adsorption, diffusion, and catalysis. Since then, zeolite science has witnessed an almost exponential growth in published papers and patents, dealing with both fundamentals issues and original applications. The proposal of new procedures for zeolite synthesis, the development of novel and sophisticated physical techniques for zeolite characterization, the discovery of new zeolitic and related microporous materials, progresses in quantum chemistry and molecular modeling of zeolites, and the application of zeolites as catalysts for organic reactions have prompted increasing interest among the scientific community. An important and harmonious interaction between various domains of Physics, Chemistry, and Engineering resulted therefrom.

This book provides an overview of the design, synthesis, and characterization of different photoactive hybrid organic-inorganic materials, based on the combination of mainly organic molecules and inorganic nanostructures, tackling their uses in different scientific fields from photonics to biomedicine. There are many examples extensively describing how the confinement of organic compounds (i.e. chromophores, photochromic molecules or photoreactants), or other photoactive compounds (i.e.metal clusters) into several microporous systems can modulate the photophysical properties and photochemical reactions leading to interesting applications. Among (ordered)-hosts, different systems of diverse nature are widely used, such as the, the 1D- or 3D- channels of zeolitic frameworks, interlayer space of 2D-clays, the organic nanospace of curcubituril and cyclodextrins or the organo-inorganic porous crystalline MOFs systems. This volume highlights the advances of these photoactive materials and aims to be an inspiration for researchers working in materials science and photochemistry, including chemists, material engineers, physicists, biologists, and medical researchers.

Recent Advances in the Science and Technology of Zeolites and Related Materials

Widely used in adsorption, catalysis and ion exchange, the family of molecular sieves such as zeolites has been greatly extended and many advances have recently been achieved in the field of molecular sieves synthesis and related porous materials. Chemistry of Zeolites and Related Porous Materials focuses on the synthetic and structural chemistry of the major types of molecular sieves. It offers a systematic introduction to and an in-depth discussion of microporous, mesoporous, and macroporous materials and also includes metal-organic frameworks. Provides focused coverage of the key aspects of molecular sieves Features two frontier subjects: molecular engineering and host-guest advanced materials Comprehensively covers both theory and application with particular emphasis on industrial uses This book is essential reading for researches in the chemical and materials industries and research institutions. The book is also indispensable for researches and engineers in R&D (for catalysis) divisions of companies in petroleum refining and the petrochemical and fine chemical industries.

These proceedings, comprising 7 plenary lectures, 100 oral and 175 poster presentations, reflect present activities in the field of microporous materials. The International Zeolite Conferences are devoted to all aspects of zeolite science and technology. The term zeolite is to be understood in its broadest sense comprising all kinds of crystalline microporous materials regardless of their composition (e.g. aluminosilicates and other metallosilicates, silica, aluminophosphates, gallophosphates etc.), occurring in nature or synthesized by man. Mesoporous silica, aluminosilicates and other metallosilicates, as recently discovered are also included. Zeolite catalysis continues to be an area of particular interest, not only the classical hydrocarbon conversions but also zeolite catalysis of oxidation reactions, formation of a greater variety of organic compounds and environmental catalysis. Much work has been done on the synthesis of zeolites and zeolite-like materials, which is reflected in the large number of contributions to these proceedings. Improvement of techniques for investigation has stimulated interest in adsorption and diffusion studies. Other areas enjoying increasing attention are modelling, theory, and novel materials.

ZEOCAT '95 is the eleventh in the series of symposia devoted to special fields of zeolite chemistry. Six plenary lectures, forty oral and forty-two poster presentations were included in the program. The accepted papers cover every aspect of catalysis on microporous materials. A significant number of the contributions describe the synthesis, modification, instrumental and chemical characterisation of zeolites and other micro- and mesoporous materials. Catalytic reactions involve hydrocarbon cracking, nucleophilic aromatic substitution, methanol to hydrocarbon conversion, hydration of acetylene, various alkylation reactions, redox transformations, Claisen rearrangement, etc.

Molecular Sieves - Science and Technology covers, in a comprehensive manner, the science and technology of zeolites and all related microporous and mesoporous materials. Authored by renowned experts, the contributions are grouped together topically in such a way that each volume of the book series deals with a specific sub-field. Volume 4 covers the characterization of molecular sieves with the help of the most important spectroscopic techniques (Characterization I), i.e. IR, Raman, NMR, EPR, UV-VIS Spectroscopy, X-ray absorption, photoelectron and Mössbauer Spectroscopy. Theory, experiment and application in selected examples are discussed.
