Abstract

In this work, the mechanism and kinetics of the preferential CO oxidation over 0.5 wt. % Au/Al2O3 catalyst was investigated. For CO oxidation, the reaction was found to follow a two-step Eley–Rideal-type mechanism, in which the formation and decomposition of the reaction intermediate took place at the gold-support interface. For the PROX case, on the other hand, Langmuir–Hinshelwood-type mechanisms seem to be also significant.
