Download or read book Structure and Reactivity of Metals in Zeolite Materials written by Joaquín Pérez Pariente and published by Springer. This book was released on 2018-09-12 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides the reader with the most up-to-date and relevant knowledge on the reactivity of metals located in zeolite materials, either in framework or extra-framework positions, and the way it is connected with the nature of the chemical environment provided by the host. Since the first report of the isomorphous substitution of titanium in the framework of zeolites giving rise to materials with unusual catalytic properties, the incorporation of many other metals have been investigated with the aim for developing catalysts with improved performance in different reactions. The continuous expansion of the field, both in the variety of metals and zeolite structures, has been accompanied by an increasing focus on the relationship between the reactivity of metal centers and their unique chemical environment. The concepts covered in this volume are of interest to people working in the field of inorganic and physical chemistry, catalysis and chemical engineering, but also for those more interested in theoretical approaches to chemical reactivity. In particular the volume is useful to postgraduate students conducting research in the design, synthesis and catalytic performance of metal-containing zeolites in both academic and application contexts.

Download or read book Mossbauer Spectroscopic Studies of Iron Y Zeolites written by M. Boudart and published by . This book was released on 1971 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mossbauer spectroscopic studies have provided a reasonably consistent picture of the structure and chemistry of iron exchanged Y zeolite. It has been demonstrated that the oxidation-reduction behavior of ferric and ferrous exchanged Y Zeolite is related and that the same chemical states of iron are formed in both materials. The reversible oxidation of the zeolite iron ions by oxygen adsorption may have important implications for catalytic oxidation. The exchange of iron ions into zeolites with different structures and silicon to aluminum ratios and the observations of reversible oxidation may allow the preparation of oxidation catalysts with unique properties and selectivity.

Download or read book Description of Input and Examples for Phreeqc Version 3 written by David L. Parkhurst and published by Createspace Independent Publishing Platform. This book was released on 2014-07-17 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: PHREEQC version 3 is a computer program written in the C and C++ programming languages that is designed to perform a wide variety of aqueous geochemical calculations. PHREEQC implements several types of aqueous models: two ion-association aqueous models (the Lawrence Livermore National Laboratory model and WATEQ4F), a Pitzer specific-ion-interaction aqueous model, and the SIT (Specific ion Interaction Theory) aqueous model. Using any of these aqueous models, PHREEQC has capabilities for (1) speciation and saturation-index calculations; (2) batch-reaction and one-dimensional (1D) transport calculations with reversible and irreversible reactions, which include aqueous, mineral, gas, solid-solution, surface-complexation, and ion-exchange equilibria, and specified mole transfers of reactants, kinetically controlled reactions, mixing of solutions, and pressure and temperature changes; and (3) inverse modeling, which finds sets of mineral and gas mole transfers that account for differences in composition between waters within specified compositional uncertainty limits.

Available in PDF, EPUB and Kindle. Book excerpt: Energy crises and global warming pose serious challenges to researchers in their attempt to develop a sustainable society for the future. Solar energy conversion is a remarkable, clean, and sustainable way to nullify the effects of fossil fuels. The findings of photocatalytic hydrogen production (PCHP) by Fujishima and Honda propose that “water will be the coal for the future”. Hydrogen is a carbon-free clean fuel with a high specific energy of combustion. Titanium oxide (TiO2), graphitic-carbon nitride (g-C3N4) and cadmium sulfide (CdS) are three pillars of water splitting photocatalysts owing to their superior electronic and optical properties. Tremendous research efforts have been made in recent years to fabricate visible or solar-light, active photocatalysts. The significant features of various oxide, sulfide, and carbon based photocatalysts for cost-effective hydrogen production are presented in this Special Issue. The insights of sacrificial agents on the hydrogen production efficiency of catalysts are also presented in this issue.

Download or read book Natural Zeolites written by G. Gottardi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zeolites form a family of minerals which have been known since the 18th century, but they remained a curiosity for scientists and collectors until 60 years ago, when their unique physicochemical properties attracted the attention of many researchers. In the past 30 years there has been an ex traordinary development in zeolite science; six International Conferences on Zeolites have been held every 3 years since 1967, and a large number of interesting contributions have been published in their proceedings. Many books, written either by individual authors or by several authors under a leading editor, have been published on these interesting silicate phases, but none has been devoted specifically to natural zeolites, even though this theme may be of interest not only to earth scientists, but also to chemists, as the in formation obtained from natural samples completes and in tegrates the characterization of many zeolites. We are trying to fill this gap on the basis of 20 years of research on natural zeolites, which we performed at the University of Modena together with many friends and colleagues. If it is in general difficult to write a scientific book with out upsetting somebody, this is particularly true for a book on natural crystals, because mineralogy is an interdisciplin ary science which covers some fields of physics, chemistry, it is almost impossible to meet every petrology, geology, and requirement.
Download or read book Zeolites Facts Figures Future written by P.A. Jacobs and published by Elsevier. This book was released on 1989-07-01 with total page 1502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work contains over 140 papers which, together, reflect the current status of zeolite science and technology encompassing high and low silica zeolites, pillared clays, molecular sieves, microporous metallosilicates, crystalline silica polymorphs, crystalline microporous aluminophosphates and their isomorphically substituted forms. The five plenary invited lectures summarize current knowledge and address a number of topical areas such as the enumeration of theoretically possible frameworks, the use of sophisticated physical methods to unravel and characterise new molecular sieve materials, the potential of molecular sieves as catalysts for chemical intermediate and commodity synthesis and conversion, the role of zeolites in fluid catalytic cracking, and new zeolitic materials. Specific aspects of zeolite science are highlighted in the ten keynote lectures of which three are on synthesis and modification, one on new materials, one on characterization, two on structure and theory, one on metals in zeolites, and two on catalytic topics. All the contributions in this book reflect the high quality of research being carried out throughout the zeolite community.
Download or read book Zeolite Microporous Solids Synthesis Structure and Reactivity written by E.G. Derouane and published by Springer Science & Business Media. 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.
