ON CORRELATION BETWEEN SURFACE STRUCTURE AND CATALYTIC ACTIVITY OF AMORPHOUS ALLOYS
The present paper is a review summarizing our results gained in the field of catalysis
over amorphous alloys. The route leading to the formation of the catalytically active phase is
presented and the factors which may play a decisive role in this process is discussed. Following
the surface characterization of amorphous alloys led to the constructions of a surface model
its modifying effects are described. Their catalytic properties are further influenced by the
structure and the morphology. These parameters are crucial to the formation of the active
metal ensembles and to the behaviour of reactants over the surface. These factors are discussed
in detail for the utilization of amorphous alloys, primarily as catalyst precursors
