This book was released on 2007-05-08 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: I knew nothing of the work of C. G. Vayenas on NEMCA until the early nineties. Then I learned from a paper of his idea (gas interface reactions could be catalyzed electrochemically), which seemed quite marvelous; but I did not understand how it worked. Consequently, I decided to correspond with Professor Vayenas in Patras, Greece, to reach a better understanding of this concept. I think that my early papers (1946, 1947, and 1957), on the relationship between the work function of metal surfaces and electron transfer reactions thereat to particles in solution, held me in good stead to be receptive to what Vayenas told me. As the electrode potential changes, so of course, does the work function at the interface, and gas metal reactions there involve adsorbed particles which have bonding to the surface. Whether electron transfer is complete in such a case, or whether the effect is on the desorption of radicals, the work function determines the strength of their bonding, and if one varies the work function by varying the electrode potential, one can vary the reaction rate at the interface. I got the idea. After that, it has been smooth sailing. Dr. Vayenas wrote a seminal article in Modern Aspects of Electrochemistry, Number 29, and brought the field into the public eye. It has since grown and its usefulness in chemical catalytic reactions has been demonstrated and verified worldwide.

This book was released on 2002 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: (cont.) The second scaffold consists of acid-base and redox functionalities affixed to a xanthene (HPX) or dibenzofuran (HPD) scaffold - Hangman porphyrins. HPX selectively encapsulates water between its acid-base and redox sites by hydrogen bonding, affording a minimalist model for the cytochrome P450 heme water channel assemblies. Comparative reactivity studies for the catalase-like disproportionation of hydrogen peroxide and the epoxidation of olefins by HPX and HPD platforms bearing acid and ester pendants reveal that the introduction of a proton-transfer network properly oriented to a redox-active platform can orchestrate catalytic 0-0 bond activation. For the catalase and epoxidation reaction types, a marked reactivity enhancement is observed for the xanthene-bridged platform with a pendant carboxylic acid, establishing that this approach can yield superior catalysts to analogs that do not control both proton and electron currencies.

This book was released on 2019 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Electro)catalysis is essential for addressing the most pressing societal and environmental challenges of this century, ranging from fossil fuel emission reduction to the production of sustainable fuels and chemicals. Among the technologies driven by (electro)catalysis are toxic gas abatement processes, greenhouse gas storage and utilization, and electrochemical energy storage and conversion devices like fuel cells, electrolyzers, and metal-air batteries. However, the field of (electro)catalysis has been historically hindered by a lack of guiding principles for materials selection and design, especially for increasingly complex materials systems such as oxides. This has stemmed from a lack of systematic studies of surface reactivity at thermodynamic conditions relevant to the reaction of interest and understanding of chemical origins of such reactivity trends. Thus, understanding the relationship between the bulk chemistry and surface reactivity can be a powerful tool to guide materials design for a wide range of (electro)catalytic processes. To drive forward the deployment of (electro)catalytic technologies, this work will first describe the need for mechanistically-driven and intuitive materials design principles. In order to develop this understanding, we then describe investigations on perovskite oxide model systems centered on oxygen-based, nitrogen-based, and carbon-based surface reactions relating to the oxygen evolution reaction (OER) structural stability for electrolysis, NOx reaction network for toxic gas abatement, and CO2 gas reactivity for gas storage and conversion applications, respectively. Next, we translate insights regarding bulk-surface relationships to the complex electrochemical CO2 reduction reaction, a reaction with a high degree of complexity for kinetics and selectivity, using the perovskite oxide materials family as a model system. We demonstrate that the bulk metal-oxygen covalency, quantified by parameters such as the O 2p-band center distance from the Fermi level, can rationalize activity trends for the production of CH4 and H2, where an intermediate covalency maximizes the former and high covalency maximizes the latter. Lastly, we investigate the role of surface coordination of Cu-based catalysts on the CO2 reduction selectivity to high energy density chemicals and fuels, highlighting the role of careful understanding of surface reactivity.

Book excerpt: Comprehensive Inorganic Chemistry II, Nine Volume Set reviews and examines topics of relevance to today’s inorganic chemists. Covering more interdisciplinary and high impact areas, Comprehensive Inorganic Chemistry II includes biological inorganic chemistry, solid state chemistry, materials chemistry, and nanoscience. The work is designed to follow on, with a different viewpoint and format, from our 1973 work, Comprehensive Inorganic Chemistry, edited by Bailar, Emeléus, Nyholm, and Trotman-Dickenson, which has received over 2,000 citations. The new work will also complement other recent Elsevier works in this area, Comprehensive Coordination Chemistry and Comprehensive Organometallic Chemistry, to form a trio of works covering the whole of modern inorganic chemistry. Chapters are designed to provide a valuable, long-standing scientific resource for both advanced students new to an area and researchers who need further background or answers to a particular problem on the elements, their compounds, or applications. Chapters are written by teams of leading experts, under the guidance of the Volume Editors and the Editors-in-Chief. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource for information in the field. The chapters will not provide basic data on the elements, which is available from many sources (and the original work), but instead concentrate on applications of the elements and their compounds. Provides a comprehensive review which serves to put many advances in perspective and allows the reader to make connections to related fields, such as: biological inorganic chemistry, materials chemistry, solid state chemistry and nanoscience Inorganic chemistry is rapidly developing, which brings about the need for a reference resource such as this that summarise recent developments and simultaneously provide background information Forms the new definitive source for researchers interested in elements and their applications; completely replacing the highly cited first edition, which published in 1973

This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemistry provides an attractive route to a sustainable chemical industry by replacing fossil fuel-derived heat with renewable electricity as the driving force for chemical synthesis. However, most studies focus on the transformation of inorganic species, while decarbonizing high-volume petrochemical transformations requires the manipulation of C(sp3)-H and C(sp3)-C(sp3) bonds. This dissertation demonstrates two approaches that leverage the unique properties of electrochemical reactions to activate the C-H and C-C bonds in small organic molecules. First, we present an outer-sphere approach to activate C(sp3)-H bonds for the sustainable synthesis of ethylene oxide from ethanol. In this two-step transformation, ethanol was first chlorinated to 2 chloroethanol using electrochemically generated chlorine radicals before reacting with OH- to form ethylene oxide in a convergent synthesis. The formation of the thermodynamically unfavorable chlorination product, 2 chloroethanol, was promoted by applying kinetic control over the chlorination site by increasing the reaction temperature. The overall process selectivity was also controlled by the catalyst material and the applied potential which dictate the rate of competitive side reactions to form acetic acid. This halide-mediated approach is generalizable to the production of other valuable chemicals through modification of the anodic chemistry. Then, we detail how mildly oxidative potentials cleave C-C bonds in short-chain alkanes on a Pt catalyst to provide insight into the inner-sphere reactivity of organic molecules at electrochemical interfaces. While this reaction does not occur at a constant potential, it can be facilitated by changing the potential throughout the reaction. The variation provides independent control over substrate adsorption, C-C bond cleavage, and reductive product desorption. Using this technique, we showed that mildly oxidizing potentials transform butane adsorbates to *CO through *CHx fragments, which can be desorbed as methane. Identifying the branchpoint between C-C fragmentation and oxygenation allowed us to design pulsed potential approaches to promote selective C-C cleavage and provide design criteria for improved fuel cell catalysts. The manipulation of adsorbed species through the applied potential is widely applicable for reaction control and investigation. By establishing the fundamental basis for these electrochemical C(sp3)-H and C(sp3)-C(sp3) bond transformations, our findings lay the groundwork for future sustainable synthesis and electrocatalytic energy storage technologies.

Download or read book Plasma Catalysis written by Annemie Bogaerts and published by MDPI. This book was released on 2019-04-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
