TRANSLATIONAL AND COLLISION-INDUCED ACTIVATION OF CH4 ON NI(111) - PHENOMENA CONNECTING ULTRA-HIGH-VACUUM SURFACE SCIENCE TO HIGH-PRESSURE HETEROGENEOUS CATALYSIS

This paper summarizes three recently observed phenomena, translational activation, collision-induced activation, and collision-induced desorption, that are either explanations or plausible explanations for the different surface chemistry at high and low reactant pressure. It also briefly describes how the high-pressure requirement can be bypassed so that surface reactions which normally occur only under high pressures of gaseous reactants can be carried out in low-pressure, UHV environments. © 1990, American Chemical Society.
