Metal-Surface Reaction Energetics: Theory and Applications to Heterogeneous Catalysis, Chemisorption, and Surface Diffusion (0471187453) cover image
This book summarizes the major developments in the theory of reaction energetics on metal surfaces and its applications to technically important phenomena. Reaction Energies on Metal Surfaces focuses on the ways of calculating the heats of adsorption and reaction activation barriers and how these energetics determine the diffusion of adsorbed species and their chemical reactivity revealing in dissociation, recombination and disproportionation.
Active researchers in the field provide a thorough coverage of the subject providing both theorists and experimentalists with a mutual understanding of the many diverse phenomena and techniques which are so critical for the steady progress of this field.
