Opis

The introduction of synthetic zeolites in the early 1950s has led to a paradigm shift in catalysis, separations, and adsorption processes. This is due to unique intrinsic properties such as crystallinity, high-surface area, acidity, and shape-selective character. However, the sole presence of micropores in these materials typically induces diffusion limitations, rendering low utilization of the zeolite volume. This book examines recent advances in the rapidly evolving area of zeolites with improved accessibility and molecular transport. Particular emphasis is given to mesoporous zeolites prepared by by the novel methodology of desilication, i.e. controlled framework silicon extraction. These materials couple the catalytic power of micropores and the facilitated access of a surrounding mesopore network. Despite its emphasis on zeolites, this book stimulates intuition into design of related nanoporous materials. The work described in this book is considered useful to those active in the field of porous materials development, characterization and application.
