摘要：

The use of a monolayer of Mo ions to stabilize and help activate Pt/Al2O3 catalysts is investigated. The monolayer of Mo is deposited using exfoliated MoS2 single molecular layers, which deposit on the alumina support as a single-layer coating. It is found that the presence of the resulting monolayer of molybdenum stabilizes the Pt against sintering to at least 800°C. It is also found that the initial activity for oxidation is enhanced substantially. It is concluded that the Mo monolayer also induces dispersion of the Pt. © 1991.
