Book Description
This volume summarises and reviews the enormous progress made over the past two decades in solid acids and bases, with emphasis on fundamental aspects and chemical principles. In recent years many new kinds of solid acids and bases have been found and synthesized. The surface properties (in particular, acidic and basic properties) and the structures of the new solids have been clarified by newly developed measurement methods using modern instruments and techniques. The characterized solid acids and bases have been applied as catalysts for diversified reactions, many good correlations being obtained between the acid-base properties and the catalytic activities or selectivities. Recently, acid-base bifunctional catalysis on solid surfaces is becoming a more and more important and intriguing field of study.It has been recognized that the acidic and basic properties of catalysts and catalyst supports play an important role in oxidation, reduction, hydrogenation, hydrocracking, etc. The effect of the preparation method and the pretreatment conditions of solid acids and bases on the acidic and basic properties, the nature of acidic and basic sites and the mechanism regarding the generation of acidity and basicity have been elucidated experimentally and theoretically. On the basis of the accumulated knowledge of solid acids and bases, it is now possible to design and develop highly active and selective solid acid and base catalysts for particular reactions. The chemistry of solid acids and bases is now being related to and utilized in numerous areas including adsorbents, sensors, cosmetics, fuel cells, sensitized pressed papers, and others. The information presented in this book will therefore be of interest to a wide-ranging readership.

Book Description
An acid that is stronger than the acid strength of 100% sulphuric acid is known as a superacid. Environmental concerns about the use of toxic liquid superacids and liquid inorganic acids in the transformation of hydrocarbons provide an impetus for a search of stable and more environmentally friendly solid acid catalysts. This book examines an important opportunity related to green chemistry where solid superacids lead to new gas- and liquid-solid phase reactions, which are environmentally benign processes in the chemical industry.

Book Description
Ion Exchange Membranes A comprehensive introduction to the electro-membrane technologies of the future An ion exchange membrane is a polymer-based membrane which can be permeable by some ions in a solution while blocking others, making them ideal for processes such as water desalination, salt concentration control, clean production and—given their electrical conductivity—power generation and energy storage etc. Recent advances have given rise to new electro-membrane processes that promise drastically to expand the applications of this technology. Scientists in both research and industry will increasingly need to draw on these membranes in vital ways with strongly positive potential environmental impact. Ion Exchange Membranes summarizes recent research into these membranes and electro-membrane processes before moving to an overview of the historical background. It then attends in detail to cutting-edge fabrication technologies and the most recent areas of use. The result is a comprehensive introduction to the design, fabrication, and applications of these increasingly essential membranes. Ion Exchange Membranes readers will also find: In-depth treatment of industrial-scale applications Detailed discussion of topics including side-chain engineering, polyacylation, superacid-catalyst polymerization, and more Analysis of electro-membrane processes such as alkaline membrane water electrolysis, solar-driven water splitting, and many more Ion Exchange Membranes is ideal for membrane scientists, materials scientists, inorganic chemists, polymer chemists, and researchers and engineers in a variety of fields working with ion exchange membranes and electro-membrane processes.
