Oxide surface materials are widely used in many applications, in particular where
chemically modified oxide surfaces are involved. Indeed, in disciplines as separations,
catalysis, bioengineering, electronics, ceramics, etc. modified oxide surfaces are very
important. In all cases, the knowledge of their chemical and surface characteristics
is of great importance for the understanding and eventual improvement of their
performances.
The purpose of this book is essentially to cover techniques and procedures
characterizing and modifying the silica surface. We hope that this book will be useful
for all those who, working at the graduate student or research worker level, are
interested in the chemistry of silica and chemically modified oxide surfaces.
The content of this book reviews the latest developments in the characterization and
chemical modification of silica surfaces. No attempt has been made to survey
exhaustively the literature of any topic. The material has been collected from recent
publications and own research work in this field. Also, recent disclosures of research
activities in the former USSR are documented in detail in the text.
The book is divided into three major parts. The first part (Part I) reviews the
characterization of the silica surface, discussing the preparation and properties of pure
silica (Chapter 1), the physical characterization of the silica surface (Chapter 2), the
chemistry of silica (Chapter 3), the quantification of the silanol number (Chapter 4),
the distribution of the silanol types and their desorption energies (Chapter 5), the
effect of surface morphology on the dehydroxilation behaviour (Chapter 6) and the
related silicate materials (Chapter 7). Part II discusses the chemical modification of....
