A Study on the Nonlinear Kinetics of CO Desorption under the Gas Ambience on Pd
Abstract:
The kinetics of CO desorption on Pd(111) has been studied by using isotope switch method under the gas-phase pressures of single isotope and mixed ones. The experiments show that the desorption kinetics is non-linear and is first order plus second order on the saturated surface. Based on the delocalized chemisorptions model and gas-surface exchange mechanism, the analytic expressions for the desorption kinetics are derived and a dynamic reasoning of the non-linear kinetics has been described in detail.
