Available in PDF, EPUB and Kindle. Book excerpt: Laser Raman Spectroscopy (LRS) has become an important tool for the in-situ structural study of electrochemical systems and processes in recent years. Following a brief introduction of the experimental techniques involved in applying LRS to electrochemical systems, we survey the literature for examples of studies in the inhibition of electrode reactions by surface films (e.g., corrosion and passivation phenomena) as well as the acceleration of reactions by electro-sorbates (electrocatalysis). We deal mostly with both normal and resonance Raman effects on fairly thick surface films in contrast to surface-enhanced Raman investigations of monolayer adsorbates, which is covered in another lecture. Laser Raman spectroelectrochemical studies of corrosion and film formation on such metals as Pb, Ag, Fe, Ni, Co, Cr, Au, stainless steel, etc. in various solution conditions are discussed. Further extension of the technique to studies in high-temperature and high-pressure aqueous environments is demonstrated. Results of studies of the structure of corrosion inhibitors are also presented. As applications of the LRS technique in the area of electrocatalysis, we cite studies of the structure of transition metal macrocyclic compounds, i.e., phthalocyanines and porphyrins, used for catalysis of the oxygen reduction reaction. 104 refs., 20 figs.

This book was released on 1999 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibrational spectroscopic and electrochemical techniques are among the most useful tools for the elucidation of corrosion-passivation phenomena in metals. The former can provide information on the structure and composition of corrosion films ''in situ'' in aqueous solution environments, while thermodynamic and kinetic information may be obtained using electrochemical techniques. In this paper, we demonstrate the application of Laser Raman Scattering (LRS) and Synchrotrons Far Infrared Reflectance Spectroscopy (SFIRS), coupled with electrochemical methods, for the determination of the structure and composition of surface films on nickel and copper in aqueous solution environment. The corrosion film on nickel has been found to consist of NiO and Ni(OH)2 in the passive region of potential and NiOOH in the transpassive region. The film on copper consists of Cu2O, CUO and Cu(OH)2. We also show for the first time that SFIRS can be used to obtain information on the adsorption of ions on a metal surface with sub-monolayer sensitivity. Adsorption of Cl−, Br−, SO−2, and PO4−3 was found to occur at gold electrodes in perchloric acid solution. We also observed that when two different ions are present in solution, the more strongly adsorbed ion determined the corrosion behavior of the metal.

This book was released on 2012-12-06 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemistry is one of the oldest branches of Physical Chemistry. Having its foundations in the work of Faraday, Arrhenius and others, it evolved from the study of transport in electrolyte solutions to that of electrode kinetics. Kinetic methods are inherently unable to identify unequivocally the species involved in a reaction. Therefore, beginning in the 70s many spectroscopic and diffraction techniques were applied to the study of the electrode-electrolyte interface, in order to identify intermediary reaction species, and even the spatial arrangement of atoms or molecules at the interface. In order to disseminate these techniques, a NATO Advanced Sutdy Institute was held at Puerto de la Cruz, Tenerife (Canary Islands, Spain) from July 2 to 15, 1988. The Institute consisted of tutorial type lecutures, poster sessions, and round-table discussions. It was attended by over 65 participants from NATO-member countries, and others from Argentina and Japan. In the present volume most of the lectures presented at the Institute have been collected. At least one chapter is devoted to each technique. Emphasis has been made on case studies, rather than theory, which can be found in textbooks and other publications. Our purpose in this book is to help the electrochemists uninitiated in spectroscopic methods to decide which techniques would be suitable for application to their particular problems. We thank all the lecturers who contributed to this volume, and even those UHPs (Unrepentant Habitual Procrastinators) who did not in spite of our urgings to do so.

This book was released on 2012-12-06 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of considerable efforts over the years to understand and combat materials degradation via corrosion processes, many challenges still remain both in the theoretical understanding of the phenomena and in seeking pratical solutions to the perennial problem. Progress has been slow due to the complexity of the processes and the systems involved. Fortunately, in recent years there has been a renaissance in the development of new electrochemical and optical techniques, as well as advances in instrumentation, which have greatly aided our quest to gain insight into the complex mechanisms involved in metallic corrosion and passivation. Numerous scientific meetings, symposia, and workshops have been held allover the world which attest to the frenzy of activities in corrosion science and technology. However, most of these conferences have dealt mainly with recent research results. There appeared to be a need to assess and disseminate our present state of knowledge in the field as regards measurement techniques, theory, and instrumentation. The present NATO Advanced Study Institute was therefore held in Viana do Castelo, Portugal from July 9 to 21, 1989. The Institute consisted of a series of tutorial lectures, poster sessions, and round-table discussions interspersed evenly over the two-week period. It was attended by 75 participants from several countries representing industry, government and university laboratories.

This book was released on 2013-03-12 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M. Bockris University of Ottawa B. E. Conway Case Western Reserve University Ernest Yeager Texas A & M University Ralph E. White Preface to Volume 8 Experimental methods in electrochemistry are becoming more diverse. This volume describes many of the new techniques that are being used as well as some of the well-established techniques. It begins with two chapters (1 and 2) on electronic instrumentation and methods for utilization of microcomputers for experimental data acquisition and reduction. Next, two chapters (3 and 4) on classical methods of electrochemical analysis are presented: ion selective electrodes and polarography.
