摘要：

Bimetallic clusters composed of V and Co were synthesized by a laser vaporization method. The reactivity of these alloy clusters toward H2 was determined by use of a fast-flow reactor in comparison with pure clusters Con. It was found that the Co12V cluster is extraordinarily stable against H2 adsorption whereas Co13 exhibits substantial reactivity toward H2. This result was explained in terms of the stable structure of Co12V where the V atom is located at the center interacting with 12 Co atoms on the surface. © 1990 American Chemical Society.
