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 fi eld 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".

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

The electrocatalytic behaviour of copper in base is of considerable relevance in processes such as electroless copper deposition which in turn is of increasing interest in the microelectronics industry. However, there are still gaps in our understanding of some of the basic features of copper as an electrocatalyst and from the work undertaken here, even on the electrochemistyr of copper in alkaline solution. The answer to this dilemma seems to reside in the Incipient Hydrous Oxide Adatom Mediator (IHOAM) approach to electrocatalysis, which entails two rather novel aspects of electrochemistry namely the active states of metals and hydrous oxide behaviour. To date much of the available data supporting the IHOAM view of electrocatalysis is based on results for electrocatalytic processes on the noble metals, gold and platinum. In the present work, the wider applicability of the IHOAM theory is shown, by extending the model to explain many electrocatalytic processes on copper in alkaline solution. The results obtained for glyoxylate electrocatalysis on copper in base are in excellent agreement with the IHOAM moder. The aldehyde functions as both an oxidant and reductant whose reduction and oxidation appear to be mediated by active copper atoms and incipient hydrous () ̲oxide species, respectively. The changeover from one reaction to the other, at ca. -0.1 V (RHE) at 60oC in 1.0 mol dm-3 NaOH solution, was related to the redox transition of the interfacial mediator species which takes place at a potential that is well within the double layer region of copper in base. The approach was extended by showing that an even more active copper surface state which mediates DMAB oxidation (hydrous oxide) and CO2 reduction (active copper atom, Cu**), exists at ca. -0.35 V on copper in alkaline solution.

Electrocatalysis applications are employed in a large number of industries worldwide, ranging from old technologies such as galvanoplasty to the most up-to-date deployments involving ultracapacitators. Recognizing electrocatalysis as a useful interfacial approach to a dynamic interdisciplinary science, Electrocatalysis: Computational, Experimental, and Industrial Aspects focuses on important developments in the field that are the most relevant to new technologies. Gathering the experiences of a collection of experts who have worked on the basic principles of electrocatalysis as it applies to theoretical physics and theoretical chemistry, the book gives readers a clear view of the problems inside electrocatalytic reactions, presenting both the limitations of electrocatalysis in the laboratory along with its possibilities in industry. Topics discussed include: The current uses of electrocatalysis Future perspectives on the field Surface physical properties and surface relaxation on noble and non-noble surfaces The quantum nature of the electron transfer Müller-Calandra, Srinivasan-Gileadi, and instantaneous nucleation-growth overlap models The production, storage, use, and delivery of hydrogen in industrial electrochemistry Theoretical approaches to current distribution on rough surfaces The use of microradiology to study electrodeposition Principles of electrochemical engineering, fuel cell reactors, and electrocatalytic reactor design Electrocatalysis of electroless plating Fundamental aspects of the corrosion of metals The book reviews four main electrochemical processes (hydrogen production, oxygen electrochemistry, energy conversion/production, and fine electroplating). Surface modified non-noble metal substrates and natural minerals as well as noble mineral catalysts are considered. The text goes beyond other books, which merely focus on progress in the application of surface science and ultra high vacuum techniques to electrochemistry. Instead, this volume offers potential industrial applications of these findings, making it a unique reference for professionals and academia alike.

The oxidation of formic acid and methanol has been stuidied on electrodes prepared by ion implanting Pt in RuO/sup 2/. Formic acid was found to oxidize readily on this catalyst without poisoning the surface.
The oxidation of formic acid and methanol has been stuidied on electrodes prepared by ion implanting Pt in RuO/sup 2/. Formic acid was found to oxidize readily on this catalyst without poisoning the surface. In the case of methanol no reaction was found to take place. Using XPS techniques, Pt was shown to have a lower binding energy than bulk Pt. This suggests that there is excess charge on this form of Pt which changes its reactivity.
