摘要：
Our recent studies of the steady-state kinetics of the N2O-CO reaction on Rh(l 10) indicate that at CO excess, the reaction rate increases with increasing temperature. At N2O excess, the reaction rate is nearly independent of temperature at T < 520 K and rapidly decreases with increasing temperature at T > 520 K. Our present analysis of the relevant data indicates that the latter feature seems to be related to surface-oxide formation. Following this line, we propose a mean-field kinetic model making it possible to describe and clarify the experiment. (c) 2007 Elsevier B.V. All rights reserved.
