Download or read book Insights into the Chemistry of Organic Structure Directing Agents in the Synthesis of Zeolitic Materials written by Luis Gómez-Hortigüela and published by Springer. This book was released on 2018-03-31 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume focuses on the host-guest chemistry of organic molecules and inorganic systems during synthesis (structure-direction). Organic molecules have been used for many years in the synthesis of zeolitic nanoporous frameworks. The addition of these organic molecules to the zeolite synthesis mixtures provokes a particular ordering of the inorganic units around them that directs the crystallization pathway towards a particular framework type; hence they are called structure-directing agents. Their use has allowed the discovery of an extremely large number of new zeolite frameworks and compositions. This volume covers the main aspects of the use of organic molecules as structure-directing agents for the synthesis of zeolites, including first an introduction of the main concepts, then two chapters covering state-of-the-art techniques currently used to understand the structure-directing phenomenon (location of molecules by XRD and molecular modeling techniques). The most recent trends in the types of organic molecules used as structure-directing agents are also presented, including the use of metal-complexes, the use of non-ammonium-based molecules (mainly phosphorus-based compounds) and the role of supramolecular chemistry in designing new large organic structure-directing agents produced by self-aggregation. In addition the volume explores the latest research attempting to transfer the asymmetric nature of organic chiral molecules used as structure-directing agents to the zeolite lattice to produce chiral enantioselective frameworks, one of the biggest challenges today in materials chemistry. This volume has interdisciplinary appeal and will engage scholars from the zeolite community with a general interest in microporous materials, which involves not only zeolite scientists, but also researchers working on metal-organic framework materials. The concepts covered will also be of interest for researchers working on the application of materials after encapsulation of molecules of interest in post-synthetic treatments. Further the work explores the main aspects of host-guest chemistry in hybrid organo-inorganic templated materials, which covers all types of materials where organic molecules are used as templates and are confined within framework-structured inorganic materials (intercalation compounds). Therefore the volume is also relevant to the wider materials chemistry community.

Download or read book Inclusion Chemistry with Zeolites Nanoscale Materials by Design written by Norman Herron and published by Springer Science & Business Media. This book was released on 1995 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zeolites, with their crystalline microporous structure, are cordial hosts to a wide variety of guests. Traditional absorption techniques, as well as X-ray diffraction and spectroscopic techniques, have contributed to a better understanding of the nature of the host materials' characteristic cavities, cages and channels. The same techniques, coupled with powerful computational methods, have given new insights into the interactions of guest molecules with their hosts. In turn, this has led to new developments in the direction of structure during zeolite synthesis as well as potentially new applications of guest-host materials. The chapters in this text describe modern research in this field, detailing some of the studies on structure direction in synthesis, characterization techniques, computational aspects, co-ordination and organometallic chemistry, photochemistry, and electronic and optical materials.
Download or read book Zeolites written by Jiří Čejka and published by . This book was released on 2008-01-01 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreword During the recent years a large number of fascinating books appeared covering the ever growing area of zeolites, zeotypes and mesoporous molecular sieves even including the emerging field of metal organic frameworks. In contrast, we decided to prepare this book focused exclusively on zeolites and zeotypes, defined as crystalline microporous materials, to show that they are still one of the most important groups of inorganic materials serving as very well defined model structures for detail kinetic and spectroscopic studies up to industrially applied catalysts for cracking, refineries, petrochemistry, synthesis of fine chemicals, and in environmental catalysis. Based on that we believe that this book on zeolites will be useful not only for students and newcomers to this field but also to all experienced researchers as a useful reference book. Preparing this book we tried to follow up the pathway starting from synthesis of zeolites and understanding of new advances in this area up to their applications in adsorption and zeolites. Authors both from academic institutions very active in this area as well as leading experts from industry were invited to prepare their contributions. While in the Introduction the editors tried to briefly outline some basic summary of the last 250 years since the description of the first natural zeolite by Swedish mineralogist Cronsted, W.J. Roth focused on the discussion of recently synthesized zeolites and zeotypes and the exploitation of the structure directing concepts for the successful synthesis of these novel structural types of zeolites. This is continued by R. Lobo, who made a great effort to evaluate the most important factors controlling the synthesis of zeolites from the point of view of the mechanism of zeolite synthesis. Many organic cations play important role in the synthesis of zeolites and J. Perez-Pariente focused his attention on their role as structure- directing agents, without which the synthesis would not proceed. In recent years synthesis of nanozeolites with particle sizes in tens of nanometers step forward. This topic is nicely covered by S. Mintova and V. Valtchev showing important factors for their synthesis together with discussing possibilities of their investigation. This is followed by the chapter of S.E. Park centered on the application of microwave irradiation to shorten the synthesis time of zeolites and to control selectivity and morphology during the synthesis. Zeolite membranes for separations and catalysis present another important area of zeolite endeavor. J. Santamaria and coworkers nicely described recent achievements in this area. Final chapter devoted to the synthesis of zeolites was written by industrial experts led by Lam. The authors focused on the critical issues of scaling up of the zeolite synthesis, which provides more detailed ideas of the critical aspects of this effort. Acidity is one of the most important features of zeolites playing the crucial role in acid-catalyzed reactions. B. Gil presented various approaches to characterization of the acidity of zeolites and discussed advantages and disadvantages of individual relevant methods. From the practical point of view main part of the book is devoted to catalysis. Chapter by R. Staudt and M. Thommes preceded these chapters describing a broad application potential of zeolites for adsorption applications. As for the catalysis, A. Martinez focused on application of zeolites in petrochemical reactions and M. Bejblová and J. Cejka highlighted many examples of catalytic potential of zeolites in fine chemical synthesis. For the first time a topic of zeolite catalysis for renewables was covered by H. van Bekkum while Z. Sobalik discussed the application of zeolites in environmental catalysis with special emphasis on deNOx processes. Industrial applications of zeolites were summarized by C. Perego and A. Carati showing many examples of the importance of zeolites in this field. Finally, C. Christensen and his group presented an emerging field of controlled synthesis of mesoporous zeolites and their catalytic potential. It was our great pleasure to work with many friends and top researchers on the preparation of this book. We would like to sincerely thank all of them for their timely reviews on selected topics and particular effort to put the book together. Last but not least we appreciate the kind invitation from the Transworld Research Network publishing house to edit this book.

This book was released on 2009-10-03 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for putting together a tutorial on zeolites came originally from my co-editor, Eric Derouane, about 5 years ago. I ?rst met Eric in the mid-1980s when he spent 2 years working for Mobil R&D at our then Corporate lab at Princeton, NJ. He was on the senior technical staff with projects in the synthesis and characterization of new materials. At that time, I managed a group at our Paulsboro lab that was responsible for catalyst characterization in support of our catalyst and process development efforts, and also had a substantial group working on new material synthesis. Hence, our interests overlapped considerably and we met regularly. After Eric moved back to Namur (initially), we maintained contact, and in the 1990s, we met a number of times in Europe on projects of joint interest. It was after I retired from ExxonMobil in 2002 that we began to discuss the tutorial concept seriously. Eric had (semi-)retired and lived on the Algarve, the southern coast of Portugal. In January 2003, my wife and I spent 3 weeks outside of Lagos, and I worked parts of most days with Eric on the proposed content of the book. We decided on a comprehensive approach that ultimately amounted to some 20+ chapters covering all of zeolite chemistry and catalysis and gave it the title Zeolite Chemistry and Catalysis: An integrated Approach and Tutorial.

This book was released on 2012-12-06 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
