Recent Studies of Chemical Interactions on Surfaces Using Molecular Beams.

摘要

Molecular beams are being used to study chemical interactions on surfaces with increasing frequency and effectiveness. During the period beginning in 1970 through the spring of 1975, the number of published papers in this field approximately doubled. It is the purpose of this article to comprehensively review the field of molecular beam studies of chemical interactions on surfaces during this period and provide a helpful perspective for the use of other workers in this field. Within the scope of this article will be included molecular beam studies of (1) chemisorption with special emphasis on 'activated chemisorption,' (2) studies of heterogeneous chemical reactions including simple unimolecular decomposition, (3) reactions with the surface of corrosion, and (4) catalytic bimolecular reactions between distinct chemical species on the surface. A discussion of the experimental details of molecular beam techniques and their application to studies of chemical interactions on surfaces has been largely avoided since this topic has been thoroughly discussed in other recent articles.
