Abstract
Using time-resolved high-resolution electron-energy-loss spectroscopy,
nonequilibrium adsorption of CO on Pt(111) has been measured and
quantitative comparison made with equilibrium absorption over the
whole range of coverage between 300 and 100 K. It is unambiguously
shown that there is no site conversion of CO between on-top and bridge
sites below 150 K. The ambiguity of equilibrium parameters derived
from equilibrium data without knowledge of nonequilibrium data is
demonstrated. An adsorbate-induced surface-reconstruction model has
been proposed to explain the adsorption kinetics of CO on Pt(111)
between 100 and 400 K.
