| Summary: | This book describes a science and technology of a new type of electrocatalysts consisting of a single atomic layer of platinum on suitable supports. This development helped overcome three major obstacles--catalysts' cost, activity, and stability--for a broad range of fuel cell applications. The volume begins with a short introduction to the science of electrocatalysis, covering four reactions important for energy conversion in fuel cells. A description follows of the properties of metal monolayers on electrode surfaces, and underpotential deposition of metals. The authors then describe the concept of Pt monolayer electrocatalysts and its implications and their synthesis by galvanic displacement of less-noble metal monolayers and other methods. The main part of the book presents a discussion of catalysts' characterization and catalytic properties of Pt monolayers for the four main reactions of electrochemical energy conversion: oxygen reduction and oxidation of hydrogen, methanol and ethanol. The book concludes with a treatment of scale-up syntheses, fuel cell tests, catalysts' stability and application prospects. Provides a basic knowledge of electrocatalysis, an understanding of existing problems of fuel cells' power sources and their application; and a discussion of syntheses, characterization, and tuning catalytic properties of new groundbreaking Pt monolayer electrocatalysts Describes in detail examples for oxygen reduction, hydrogen, methanol and ethanol oxidation reactions Examines the enormous environmental benefit expected from automotive application of the H2/O2 fuel cell given its benign reaction products of electric current and water The first book on the important subject of platinum monolayer electrocatalysts, which has a major impact on research and development of new catalysts.
