Heterogenous Photochemical Electron Transfer

The present monograph attempts to unify these diverse and exciting new developments within a common framework. First, the physical principles underlying heterogenous electron-transfer processes are outlined in a concise way and are compared to the homogeneous counterpart. This analysis includes the notion of the Fermi level in liquids and solids as well as the distribution of electronic energy levels in solids and liquids. A comparison is made between the salient kinetic features of homogeneous and heterogeneous electron transfer reactions. This establishes the basis for the subsequent treatment of the transduction of excitation energy and photo-initiated electron transfer in organized molecular assemblies, such as micelles, vesicles and monolayers. Transmembrane redox processes are critically reviewed. Particular attention is given to semiconductor electrodes and particles. This includes a discussion of quantum size effects, the nature of space charge layers as well as surface states and the dynamics of charge carrier-induced redox reactions at the semiconductor solution interface. These processes are of fundamental importance in such diverse fields as photochromism, electrochromic displays, electroreprography and photography, information storage, photocatalysis, photodegradation of paints, and solar energy conversion.

This second volume of a two-volume set develops the tools necessary to study and understand systems in which chemical reactions can take place, and establishes criteria for chemical equilibrium. For complex systems, the number of independent reactions and their nature are determined systematically; the effect of external factors on chemical equilibria is analyzed and illustrated; the formalism necessary to study ideal and real solutions is provided; and various standard states in use and the corresponding activity coefficients are defined. The volume includes problems and solutions.

Universal-Publishers

This is volume 1 of a two-volume set. A primarily phenomenological approach was selected to keep chemical thermodynamics accessible to beginners. Coverage encompasses the fundamental aspects of thermodynamics, for students in chemistry, chemical engineering, and material sciences. Most of the specific mathematical tools are presented directly in the text; problems and solutions are provided.
