Surface reactions are important in many catalytic processes, and their
kinetics are the focus of intensive research. One of the problems in these
studies is that many of the techniques used require high vacuum, so reaction
conditions, especially pressure, are often unrealistic. Rotermund et al.
(p. 608) have developed optical techniques that allow the real-time observation
of reaction kinetics of carbon monoxide oxidation on a platinum surface from
high vacuum to atmospheric pressures. They also observed new phenomena in
pattern formation.
