PREFACE
THE PHYSICAL BASIS FOR HETEROGENEOUS CATALYSIS is
the proceedings of the ninth Battelle Colloquium in the Materials Sciences,
held in Gstaad, Switzerland, September 2-6, 1974. It took as its theme the
application of modern theoretical and experimental surface physics to
heterogeneous catalysis. Progress in the field by classical chemical methods
seemed to have slowed down, at a time when the need for better catalysts
was particularly great. The Organizing Committee thought it might be
possible to accelerate progress by the application of the powerful techniques
evolved in recent years for studying atomically clean surfaces. However, the
translation of ideas derived from clean single crystal surfaces with well
characterized chemisorbed layers to real catalysts with high ratios of surface
to mass on which reactions were taking place and requiring transport of
mass and energy is a giant step, raising many questions and requiring
thorough discussion by surface physicists on the one hand and catalytic
chemists on the other. The 1974 Battelle Colloquium provided a forum for
this exchange.
As its usual custom, the Colloquium started the first day of introduc
tory lectures by three distinguished scientists who have contributed impor
tantly over many years to this field. On following days, the overall field was
divided into the following sessions:
Experiments on Clean Metal Surfaces with Adsorbates
Theory of Chemisorption
