This book was released on 1976 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last 50 years, one of the objectives of heterogeneous catalysis research has been to identify the surface atoms, the active sites, which catalyze each step in a reaction of interest. In general, the technique used is to vary the surface structure of the catalyst in a systematic way, and to observe the changes in activity and selectivity that may result. Three forms of metal catalysts have been used in these studies: Metal particles dispersed on porous supports, metal films and metal crystals. Crystals are used because their surface morphology can be determined with electron diffraction methods, and various structural features can be introduced in a controlled manner. In this work, five different faces of platinum single crystals were used to investigate the catalytic activity of three surface features: Flat, close-packed planes of metal atoms, edge atoms present at the termination of a flat plane and corner atoms present at kinks, or zig-zags, in atomic steps. These may be thought of as models of atom groupings which may be present on metal particles in industrial catalysts. Several hydrocarbon-hydrogen reactions, representative of those that occur in commercial petroleum reforming processes, were studied.

This book was released on 1992 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conversion reactions of hydrocarbons over Pt-Re model catalyst surfaces modified by sulfur and alumina have been studied. A plasma deposition source has been developed to deposit Pt, Re, and Al on metal substrates variable coverage in ultrahigh vacuum without excessive heating. Conversion of n-hexane was performed over the Re-covered Pt and Pt-covered Re surfaces. The presence of the second metal increased hydrogenolysis activity of both Pt-Re surfaces. Addition of sulfur on the model Catalyst surfaces suppressed hydrogenolysis activity and increased the cyclization rate of n-hexane to methylcyclopentane over Pt-Re surfaces. Sulfiding also increased the dehydrogenation rate of cyclohexane to benzene Over Pt-Re surfaces. It has been proposed that the PtRe bimetallic catalysts show unique properties when combined with sulfur, and electronic interactions exist between platinum, rhenium and sulfur. Decomposition of hydrocarbons on the sulfur-covered Pt-Re surfaces supported that argument. For the conversion of 1-butene over the planar Pt/AlO(subscript x), the addition of Pt increased the selectivity of hydrogenation over isomerization.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalytic reactions of cyclohexene, benzene, n-hexane, 2-methylpentane, 3-methylpentane, and 1-hexene on platinum catalysts were monitored in situ via sum frequency generation (SFG) vibrational spectroscopy and gas chromatography (GC). SFG is a surface specific vibrational spectroscopic tool capable of monitoring submonolayer coverages under reaction conditions without gas-phase interference. SFG was used to identify the surface intermediates present during catalytic processes on Pt(111) and Pt(100) single-crystals and on cubic and cuboctahedra Pt nanoparticles in the Torr pressure regime and at high temperatures (300K-450K). At low pressures (

Available in PDF, EPUB and Kindle. Book excerpt: Now updated-the current state of development of modern surface science Since the publication of the first edition of this book, molecular surface chemistry and catalysis science have developed rapidly and expanded into fields where atomic scale and molecular information were previously not available. This revised edition of Introduction to Surface Chemistry and Catalysis reflects this increase of information in virtually every chapter. It emphasizes the modern concepts of surface chemistry and catalysis uncovered by breakthroughs in molecular-level studies of surfaces over the past three decades while serving as a reference source for data and concepts related to properties of surfaces and interfaces. The book opens with a brief history of the evolution of surface chemistry and reviews the nature of various surfaces and interfaces encountered in everyday life. New research in two crucial areas-nanomaterials and polymer and biopolymer interfaces-is emphasized, while important applications in tribology and catalysis, producing chemicals and fuels with high turnover and selectivity, are addressed. The basic concepts surrounding various properties of surfaces such as structure, thermodynamics, dynamics, electrical properties, and surface chemical bonds are presented. The techniques of atomic and molecular scale studies of surfaces are listed with references to up-to-date review papers. For advanced readers, this book covers recent developments in in-situ surface analysis such as high- pressure scanning tunneling microscopy, ambient pressure X-ray photoelectron spectroscopy, and sum frequency generation vibrational spectroscopy (SFG). Tables listing surface structures and data summarizing the kinetics of catalytic reactions over metal surfaces are also included. New to this edition: A discussion of new physical and chemical properties of nanoparticles Ways to utilize new surface science techniques to study properties of polymers, reaction intermediates, and mobility of atoms and molecules at surfaces Molecular-level studies on the origin of the selectivity for several catalytic reactions A microscopic understanding of mechanical properties of surfaces Updated tables of experimental data A new chapter on "soft" surfaces, polymers, and biointerfaces Introduction to Surface Chemistry and Catalysis serves as a textbook for undergraduate and graduate students taking advanced courses in physics, chemistry, engineering, and materials science, as well as researchers in surface science, catalysis science, and their applications.

Available in PDF, EPUB and Kindle. Book excerpt: In the new edition of this widely praised textbook, all the chapters have been revised and the authors have brought the work completely up to date by the addition of new material on numerous topics. In recent years, solid state chemistry has emerged as a very important element of mainstream chemistry and materials science. Students, teachers and researchers need to understand the chemistry of solids because of the crucial role this plays in determining the properties of materials. An understanding of solid state chemistry is also essential in materials design, and many fascinating relationships between the structure and properties of solids have been discovered by chemists. This text requires only an understanding of basic physics, chemistry and crystallography, and is enhanced with the most recent examples, case studies and references. It will be of value to advanced students and researchers studying solid state chemistry and materials science as a text and reference work.
