Nanocatalysis, a subdiscipline of nanoscience, seeks to control chemical reactions by changing the size, dimensionality, chemical composition, and morphology of the reaction center and by changing the kinetics using nanopatterning of the reaction center. This book offers a detailed pedagogical and methodological overview of the field. Readers discover many examples of current research, helping them explore new and emerging applications.

Industry Reviews

From the reviews:

"This book is one in the series Nanoscience and Technology by Springer. It should be useful to chemists, chemical engineers, and material scientists entering the field of nanocatalysts as well as to experts already in the area. ... this book on the whole is an excellent contribution. It could be used as a textbook, reference, and starting point for other books in this series. It is easy to read and well organized as well as contains a significant number of graphics of all types." (Steven L. Suib, Journal of the American Chemical Society, Vol. 129 (21), 2007)
