摘要：
Alumina-supported bimetallic Pt-Au catalysts appeared to be superior to that containing Pt alone in oxidation of CO and propane. Such a catalytic behaviour in combination with previous physical characterization data suggests that Pt and Au remain intimately mixed in the form of Pt-Au bimetallic particles and that the presence of Au in these particles modifies the behaviour of Pt. Reasons for the occurrence of this synergistic effect are discussed.
