This book was released on 2015 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two main categories of heterogeneous catalysts are metal and metal oxide which catalyze 80% chemical reactions at solid-gas and solid-liquid interfaces. Metal oxide catalysts are much more complicated than metal catalysts. The reason is that the cations of the metal atoms could exhibit a few different oxidation states on surface of the same catalyst particle such as Co3O4 or change of their oxidation states under different reactive environments. For a metal catalyst, there is only one oxidation state typically. In addition, surface of a metal oxide can be terminated with multiple surface functionalities including O atoms with different binding configurations and OH group. For metal, only metal atoms are exposed typically. Obviously, the complication of surface chemistry and structure of a metal oxide makes studies of surface of an oxide catalyst very challenging. Due to the complication of surface of a meal oxide, the electronic and geometric structures of surface of a metal oxide and the exposed species have received enormous attention since oxide catalysts catalyze at least 1/3 chemical reactions in chemical and energy industries. Understanding of catalytic reactions on early transition metal oxide-based catalysts is fundamentally intriguing and of great practical interest in energy- and environment-related catalysis. Exploration of surface chemistry of oxide-based catalysts at molecular level during catalysis has remained challenging though it is critical in deeply understanding catalysis on oxide-based catalysts and developing oxide-based catalysts with high activity and selectivity. Thus, the overall objective of this project is to explore surface chemistry and structure of early transition metal oxide-based catalysts through in-situ characterization of surface of catalysts, measurements of catalytic performances, and then build an intrinsic correlation of surface chemistry and structure with their catalytic performances in a few important catalytic reactions, and essentially fundamentally understand catalytic mechanism. Furthermore, this correlation will guide the design of catalysts with high activity and selectivity.
Book Synopsis Advances in Catalysis by : Bruce C. Gates
Download or read book Advances in Catalysis written by Bruce C. Gates and published by Academic Press. This book was released on 2001-05-14 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface science emerged in the 1960s with the development of reliable ultrahigh vacuum apparatus, providing exact structures of surfaces of metal single crystals, information about their compositions, and relationships between surface structure and composition and catalytic reaction rates. Catalysis, the acceleration of a chemical reaction by a catalyst (substance), provided much of the driving force for the early development of surface science. As surface science continues its rapid development, this book illustrates how it is still driven by the challenges of catalysis and how both theory and scanning tunneling microscopy have forcefully emerged as essential tools. It is also evident how surface science continues to serve as the foundation of catalytic science. This is a compendium written by leading surface scientists presenting an incisive assessment of up-to-date theoretical and experimental results constituting the foundation of fundamental understanding of surface catalysis.

Book Synopsis Theoretical Aspects of Transition Metal Catalysis by : Gernot Frenking
Download or read book Theoretical Aspects of Transition Metal Catalysis written by Gernot Frenking and published by Springer Science & Business Media. This book was released on 2005-06-23 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal catalysis belongs to the most important chemical research areas because a ubiquitous number of chemical reactions are catalyzed by transition metal compounds. Many efforts are being made by industry and academia to find new and more efficient catalysts for chemical processes. Transition metals play a prominent role in catalytic research because they have been proven to show an enormous diversity in lowering the activation barrier for chemical reactions. For many years, the search for new catalysts was carried out by trial and error, which was costly and time consuming. The understanding of the mechanism of the catalytic process is often not very advanced because it is difficult to study the elementary steps of the catalysis with experimental techniques. The development of modern quantum chemical methods for calculating possible intermediates and transition states was a breakthrough in gaining an understanding of the reaction pathways of transition metal catalyzed reactions. This volume, organized into eight chapters written by leading scientists in the field, illustrates the progress made during the last decade. The reader will obtain a deep insight into the present state of quantum chemical research in transition metal catalysis.

Book Synopsis Catalysis by Precious Metals, Past and Future by : Marcela Martinez Tejada
Download or read book Catalysis by Precious Metals, Past and Future written by Marcela Martinez Tejada and published by MDPI. This book was released on 2020-04-15 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of the precious metals is shiny and resistant. Although expensive and potentially replaceable by transition metal catalysts, precious metal implementation in research and industry shows potential. These metals catalyze oxidation and hydrogenation due to their dissociative behavior toward hydrogen and oxygen, dehydrogenation, isomerization, and aromatization, etc. The precious metal catalysts, especially platinum-based catalysts, are involved in a variety of industrial processes. Examples include Pt–Rh gauze for nitric acid production, the Pt/Al2O3 catalyst for cyclohexane and propylene production, and Pd/Al2O3 catalysts for petrochemical hydropurification reactions, etc. A quick search of the number of published articles in the last five years containing a combination of corresponding “metals” (Pt, Pd, Ru, Rh and Au) and “catalysts” as keywords indicates the importance of the Pt catalysts, but also the continuous increase in the contribution of Pd and Au. This Special Issue reveals the importance of precious metals in catalysis and focuses on mono- and bi-metallic formulations of any supported precious metals and their promotional catalytic effect of other transition metals. The application of precious metals in diverse reactions, either homogeneous or heterogeneous, and studies of the preparation, characterization, and applications of the supported precious metal catalysts, are presented.

Book Synopsis Understanding Catalyst Structure-performance Relationships Through Precise Synthesis and in Situ Characterization by : Arun Somayaji Asundi
Download or read book Understanding Catalyst Structure-performance Relationships Through Precise Synthesis and in Situ Characterization written by Arun Somayaji Asundi and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous catalysis will play an important role in facilitating chemical reactions with sustainable energy conversion and environmental applications. The performance of a catalyst can be affected by many different physical, chemical, and electronic properties of the material. The relationships between these properties and catalytic reactivity are not well-understood and as a result, the design of high-performance catalysts has been a significant challenge. In this dissertation, we synthesize catalysts using precise methods, including atomic layer deposition (ALD) and colloidal nanocrystal synthesis. By analyzing the properties of these controlled catalytic materials during reaction using in situ methods, we understand the relationships between structure and performance. This strategy is applied to the study of several catalytic systems for sustainable energy and environmental processes. One promising pathway towards the long-term production of fuels and chemicals is through the catalytic conversion of syngas to higher oxygenates. Several classes of catalysts have emerged as promising candidates for direct higher oxygenate synthesis from syngas: rhodium-based materials, mixed Fischer-Tropsch and methanol synthesis metals, and alternatives to pure metals. In the first part of this dissertation, we study the properties of one example catalyst from each of these classes. The last two studies in this dissertation highlight general design strategies and principles in the study of heterogeneous catalysts. We show the importance of impurity control in achieving the desired catalytic performance, a factor that is often overlooked in catalyst design. Finally, we develop a procedure combining ALD and colloidal nanocrystal synthesis that can be used to study metal-support interaction in a wide variety of catalyst systems. Throughout this dissertation, emphasis is placed on structure-performance relationships, controlled catalyst synthesis using atomically precise methods, and in situ characterization. We show how an understanding of the effects of physical and chemical catalyst properties on reactivity can be used to intelligently design higher performance catalysts. Precise synthesis methods play an important role in elucidating these structure-performance relationships and in enabling the synthesis of catalytic materials with the desired nanoscale properties. Characterization of catalyst structures are further enabled by in situ methods, which allow active sites and surface characteristics to be identified. The results in this dissertation contribute to and provide guidance for the design, synthesis, and characterization of high-performance heterogeneous catalysts.
