Book Description
Catalysts speed up a chemical reaction or allow for reactions to take place that would not otherwise occur. The chemical nature of a catalyst and its structure are crucial for interactions with reaction intermediates. An electrocatalyst is used in an electrochemical reaction, for example in a fuel cell to produce electricity. In this case, reaction rates are also dependent on the electrode potential and the structure of the electrical double-layer. This work provides a valuable overview of this rapidly developing field by focusing on the aspects that drive the research of today and tomorrow. Key topics are discussed by leading experts, making this book a must-have for many scientists of the field with backgrounds in different disciplines, including chemistry, physics, biochemistry, engineering as well as surface and materials science. This book is volume XIV in the series "Advances in Electrochemical Sciences and Engineering".

Book Description
This volume discusses the theoretical fundamentals and potential applications of the original electro-Fenton (EF) process and its most innovative and promising versions, all of which are classified as electrochemical advanced oxidation processes. It consists of 15 chapters that review the latest advances and trends, material selection, reaction and reactor modeling and EF scale-up. It particularly focuses on the applications of EF process in the treatment of toxic and persistent organic pollutants in water and soil, showing highly efficient removal for both lab-scale and pre-pilot setups. Indeed, the EF technology is now mature enough to be brought to market, and this collection of contributions from leading experts in the field constitutes a timely milestone for scientists and engineers.

Book Description
Proton exchange membrane (PEM) fuel cells are promising clean energy converting devices with high efficiency and low to zero emissions. Such power sources can be used in transportation, stationary, portable and micro power applications. The key components of these fuel cells are catalysts and catalyst layers. “PEM Fuel Cell Electrocatalysts and Catalyst Layers” provides a comprehensive, in-depth survey of the field, presented by internationally renowned fuel cell scientists. The opening chapters introduce the fundamentals of electrochemical theory and fuel cell catalysis. Later chapters investigate the synthesis, characterization, and activity validation of PEM fuel cell catalysts. Further chapters describe in detail the integration of the electrocatalyst/catalyst layers into the fuel cell, and their performance validation. Researchers and engineers in the fuel cell industry will find this book a valuable resource, as will students of electrochemical engineering and catalyst synthesis.

Book Description
This thesis addresses theoretical aspects of systems of relevance to energy conversion, energy storage and the nitrogen cycle, as studied by rotating disk and ring-disk electrode techniques. In particular, the non-linear character of Koutecky-Levich plots often reported in the literature for the oxygen reduction reaction, ORR, and the hydrogen peroxide reduction, HPRR, have been ascribed to the interplay between mass transport of intermediates away from the electrode surface and electrode kinetics. Also assessed was the validity of XH2O2 , a popularfigure of merit used to rank the efficacy of electrocatalysts towards the ORR. In another set of studies, numerical simulations were performed to determine the amount of superoxide produced at the disk of a rotating ring-disk electrode as detected by a functionalized concentric ring electrode.Also examined were systems involving partially-active surfaces involving in one case bromide adsorbed on Pt as a poisoning species for the ORR and HPR and bromide adsorption on Au as an electrocatalyst for the reduction of hexaaquairon(III) ion in aqueous electrolytes. In both cases, very small effects very found for bromide at small coverages. In related studies involving nanoparticles of electrocatalysts dispersed on otherwise inert supports, a full30theoretical analysis for thin films of such materials bonded to a rotating disk electrode yielded results which support the use of a modified Koutecky-Levich equation for the determination of rate constants for first order reactions.Finally, two further reactions of interest were studied, namely the bromide-bromine- tribromide reaction couple, where it was accurately predicted that negligible effects on the current would result from the formation of tribromide, as well as the reduction of hydroxylamine on adsorbed hemin on glassy carbon, for which a model was proposed that could account semiquantitatively for data collected with a RDE. Lastly, theoretical aspects of ohmic microscopy were investigated that served to validate interpretation of experimental data in terms of a primary current distribution.

Book Description
Redox-Active Ligands Authoritative resource showcasing a new family of ligands that can lead to better catalysts and promising applications in organic synthesis Redox-Active Ligands gives a comprehensive overview of the unique features of redox-active ligands, describing their structure and synthesis, the characterization of their coordination complexes, and important applications in homogeneous catalysis. The work reflects the diversity of the subject by including ongoing research spanning coordination chemistry, organometallic chemistry, bioinspired catalysis, proton and electron transfer, and the ability of such ligands to interact with early and late transition metals, lanthanides, and actinides. The book is divided into three parts, devoted to introduction and concepts, applications, and case studies. After the introduction on key concepts related to the field, and the different types of ligands and complexes in which ligand-centered redox activity is commonly observed, mechanistic and computational studies are described. The second part focuses on catalytic applications of redox-active complexes, including examples from radical transformations, coordination chemistry and organic synthesis. Finally, case studies of redox-active guanidine ligands, and of lanthanides and actinides are presented. Other specific sample topics covered include: An overview of the electronic features of redox-active ligands, covering their historical perspective and biological background The versatility and mode of action of redox-active ligands, which sets them apart from more classic and tunable ligands such as phosphines or N-heterocyclic carbenes Preparation and catalytic applications of complexes of stable N-aryl radicals Metal complexes with redox-active ligands in H+/e- transfer transformations By providing up-to-date information on important concepts and applications, Redox-Active Ligands is an essential reading for researchers working in organometallic and coordination chemistry, catalysis, organic synthesis, and (bio)inorganic chemistry, as well as newcomers to the field.
