Available in PDF, EPUB and Kindle. Book excerpt: The systematic study of the adsorption of organic compounds on electrodes began with the comprehensive survey of adsorption on mercury carried out by Gouy in the first decade of this century. His studies with the capillary electrometer are still useful but do not lend themselves to detailed quantitative analysis. A more de tailed study of a few systems by Frumkin in his thesis (1919) led him to propose a quantitative phenomenological theory of organic adsorption (1925, 1926) at almost the same time as Stern proposed the model of the electrical double layer which remains the picture accepted in general terms today. The attempt at a molecular model made by Butler (1929) should be more satisfying but up to the pres ent the formidable difficulties of a molecular theory of interfacial phenomena have prevented the full interpretation of experimental results along these lines. In his work with Proskurnin (1935), Frumkin is also respon sible for the major experimental advance in the demonstration that reliable measurements of the capacity of an electrode-solution interface can be obtained provided that the work is carried out under conditions of scrupulous cleanliness. Even so, preCise mea surements of double layer capacities were not obtained until Grahame (1941) showed how convenient and reliable the dropping mercury electrode was the for these studies. This method and the hanging drop electrode remain the preferred methods for study of adsorp tion on mercury. Solid electrodes present a more difficult problem.

Available in PDF, EPUB and Kindle. Book excerpt: Electrochemisty at Metal and Semiconductor Electrodes covers the structure of the electrical double layer and charge transfer reactions across the electrode/electrolyte interface. The purpose of the book is to integrate modern electrochemistry and semiconductor physics, thereby, providing a quantitative basis for understanding electrochemistry at metal and semiconductor electrodes. Electrons and ions are the principal particles which play the main role in electrochemistry. This text, therefore, emphasizes the energy level concepts of electrons and ions rather than the phenomenological thermodynamic and kinetic concepts on which most of the classical electrochemistry texts are based. This rationalization of the phenomenological concepts in terms of the physics of semiconductors should enable readers to develop more atomistic and quantitative insights into processes that occur at electrodes. The book incorporates many traditional disciplines of science and engineering such as interfacial chemistry, biochemistry, enzyme chemistry, membrane chemistry, metallurgy, modification of solid interfaces, and materials' corrosion. The text is intended to serve as an introduction for the study of advanced electrochemistry at electrodes and is aimed towards graduates and senior undergraduates studying materials and interfacial chemistry or those beginning research work in the field of electrochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: This book had its nucleus in some lectures given by one of us (J. O’M. B. ) in a course on electrochemistry to students of energy conversion at the University of Pennsyl- nia. It was there that he met a number of people trained in chemistry, physics, biology, metallurgy, and materials science, all of whom wanted to know something about electrochemistry. The concept of writing a book about electrochemistry which could be understood by people with very varied backgrounds was thereby engendered. The lectures were recorded and written up by Dr. Klaus Muller as a 293-page manuscript. At a later stage, A. K. N. R. joined the effort; it was decided to make a fresh start and to write a much more comprehensive text. Of methods for direct energy conversion, the electrochemical one is the most advanced and seems the most likely to become of considerable practical importance. Thus, conversion to electrochemically powered transportation systems appears to be an important step by means of which the difficulties of air pollution and the effects of an increasing concentration in the atmosphere of carbon dioxide may be met. Cor- sion is recognized as having an electrochemical basis. The synthesis of nylon now contains an important electrochemical stage. Some central biological mechanisms have been shown to take place by means of electrochemical reactions. A number of American organizations have recently recommended greatly increased activity in training and research in electrochemistry at universities in the United States.

This book was released on 2013-03-09 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume contains five chapters covering areas of contemporary interest in the fields of electrolyte solutions, the state of solvent molecules at electrode surfaces, charged colloid interfaces, surface chemistry of oxide electrodes and electro chemistry, and bioelectrochemistry of charge transfer complexes. The first chapter, by Barthel, Wachter, and Gores, covers the topic of conductance of nonaqueous pro tic and aprotic electro lyte solutions. This field is not only of intrinsic interest in itself, illustrating the important departures of ion-transport behavior in organic solvents from that, more well known, in water, but the information and extensive new data presented in this chapter will be of interest to those working with nonaqueous alkali-metal batteries where the conductivity and ion-association behavior of electrolytes in various solvents other than water is of great importance. The second chapter is devoted to a very fundamental and ubiquitous aspect of electrochemistry of electrodes: the state of solvent molecules, adsorbed and oriented, at their surfaces. The role of solvent adsorption and orientation in double-layer proper ties, it will be recalled, remained poorly understood until the early 1960s. This chapter, by Trasatti, gives a thorough account of the present state of knowledge of solvent orientation at electrode interfaces and of the unsuspected (until recent years) role it plays in properties of the double layer and in determining the potential profile at charged metal surfaces in solution.

Available in PDF, EPUB and Kindle. Book excerpt: Computational techniques based on density functional theory (DFT) and experimental methods based on electrochemistry (EC), electrochemical scanning tunneling microscopy (EC-STM), and high-resolution electron energy loss spectroscopy (HREELS) were employed to study the adsorption of (i) sulfuric acid on Pd(111), (ii) benzene on Pd(111), (iii) hydroquinone/benzoquinone on Pd(111), (iv) hydroquinone sulfonate/benzoquinone sulfonate on Pd(111), (v) 2,3-dimethylhydroquinone/2,3-dimethylbenzoquinone on Pd(111) and polycrystalline Pd, (vi) hydrogen on 1-6 monolayers (ML) of Pd deposited on a Pt(111) substrate, and (vii) a thiolated iron hydrogenase model complex on polycrystalline Au. In situ EC-STM and DFT investigations of sulfuric acid on a Pd(111) surface indicated that two layers of water molecules and hydronium ions are assembled, non-co-planar with one another, between the rows of surface-coordinated sulfate anions; the layer that is slightly elevated is composed of hydronium counter cations. The STM images of benzene chemisorbed on a Pd(111) electrode surface were simulated and the results suggested that, when the potential of the Pd electrode is held at 0.3 V, benzene is chemisorbed on a 3-fold site; while at 0.55 V, the molecule is adsorbed on a position between a 3-fold and a 2-fold site. Computational and experimental results implied that at low concentrations, hydroquinone sulfonate undergoes oxidative chemisorption forming benzoquinone sulfonate (BQS) on the Pd(111) surface, BQS adopts a flat orientation in which the quinone ring is centered over a 2-fold site, and the C-H and C-S bonds are no longer co-planar with the quinone ring and are slightly tilted, directed away from the surface. At very dilute concentrations, when hydroquinone (H2Q) undergoes oxidative chemisorption producing benzoquinone oriented flat, albeit with a slight tilt, on the Pd(111) surface, the flat-adsorbed quinone ring is centered on a bridge site where the C2 axis is rotated 30° from the [110] direction of the metal substrate, the p-oxygen atoms are located above two-fold sites, and the ring is slightly puckered with the C-H bonds tilted away from the surface at approximately 20°. When 2,3-dimethylH2Q is chemisorbed on the Pd surface, at low concentrations, 2,3-dimethylH2Q is oxidatively chemisorbed producing 2,3-dimethyl-1,4-benzoquinone oriented flat on the surface, the flat-adsorbed rings are centered above 2-fold sites wherein the C=O bonds are pointing 30° from the [110] direction of the substrate, the para-oxygen atoms are located above bridge sites, the peripheral bonds are tilted away from the surface at ca. 20°, and at higher concentrations, oxidative chemisorption occurs through activation of the ring's C-H bonds yielding edge-oriented 2,3-dimethylH2Q. Electrochemistry and DFT results also implied that at 1-2 ML of Pd on Pt(111), hydrogen is only adsorbed on a hollow site while at 3 ML of Pd or more, atomic hydrogen may be chemisorbed on the 3-fold site or absorbed in the octahedral hole underneath the hollow site. Using Au electrodes, an unbound iron hydrogenase analogue complex studied was found to slightly catalyze the H2 evolution process. However, when the complex was immobilized unto the Au surface, the electrocatalytic activity was greatly improved.

Available in PDF, EPUB and Kindle. Book excerpt: The gradual emergence during the last decade of the study of the mechanism of electrode reactions from the dark ages has given stimulus to a consideration of the double layer at metal-solution interfaces, which extends far outside the classical experimental studies of the capacitance of the mercury solution interface made during the 1950's by D. C. Grahame at Amherst College, Massachusetts. The central aspect of the study of an electrode reaction is the elucidation of its path and rate-determining step. Two fields are, however, prerequisites for such studies. First, it must be known what species are in the bulk of the solution, for these will seldom be simple ones such as H30~ and this study ("complex ions") has been made with both extent and depth. Second, the occupancy of the surface of the electrocatalyst and the associated field gradients must be known as a function of position in the double layer. Such "maps of the double layer" can be given with reasonable certainty up to concentrations of about 1 N for mercury in contact with solutions of inorganic ions. However, this is-or was until very recently-the extent of the know ledge. The problems confronting a fundamental approach to the rational development of, e.g., fuel cell catalysis were therefore considerable.

Book excerpt: Prof. Jerzy Sobkowski starts off this 31st volume of Modern Aspects of Electrochemistry with a far-ranging discussion of experimental results from the past 10 years of interfacial studies. It forms a good background for the two succeeding chapters. The second chapter is by S. U. M. Khan on quantum mechanical treatment of electrode processes. Dr. Khan’s experience in this area is a good basis for this chapter, the contents of which will surprise some, but which as been well refereed. Molecular dynamic simulation is now a much-used technique in physical electrochemistry and in the third chapter Ilan Benjamin has written an account that brings together information from many recent publications, sometimes confirming earlier modeling approaches and sometimes breaking new territory. In Chapter 4, Akiko Aramata’s experience in researching single crystals is put to good advantage in her authoritative article on under- tential deposition. Finally, in Chapter 5, the applied side of electrochemistry is served by Bech-Neilsen et al. in the review of recent techniques for automated measurement of corrosion. J. O’M.

Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Electrode Processes discusses "electrodics" or the science dealing with the transfer of an electric charge between a solid and liquid phase. This book reviews the applications of electrodics, the history of electrochemistry, and the basic definitions and concepts of the galvanic cell. This text also deals with the rate expressions associated with the different types of electrode reaction mechanism including the passing of Faradaic current, the current-voltage curve, mass transport overpotential, and the influence of surface structure on electrode processes. This book describes the electrode-solution interphase at equilibrium, the properties of such interphase, and the ways it can influence electrode kinetics. Any electrode reaction involves several steps and can be influenced by diffusion, adsorption and other parameters. The techniques to study electrode reactions and the electrode-solution interphase consists of equilibrium measurements, steady state measurement, and transient measurement. This text also describes the significant and potential uses of electrodics in technology which need less expensive equipment compared to using spectrophotometric techniques. This book is suitable chemists, for advanced students in analytical chemistry, physics, thermodynamics, and related subjects.
