Catalytically-active metallic glasses containing at least one element from a subgroup of the periodic system and at least one element from a main group of the periodic system. Process for the production of catalytically-active metallic glasses where the metallic glass is produced from at least one element from a subgroup of the periodic system and at least from one element from a main group of the periodic system. The metallic glasses are activated by self-activation or by an oxidative and/or reductive treatment. The catalytically-active metallic glasses can be used as hydrogenation oxidation or isomerization catalysts.
Process comprising catalytically synthesizing ammonia from nitrogen and hydrogen using a vitreously-rigidified metallic glass consisting of (i) Fe and Zr or (ii) Fe, Zr and Mo, as the catalyst.
Process comprising catalytically synthesizing ammonia from nitrogen and hydrogen using a vitreously-rigidified metallic glass consisting as the catalyst, of (i) Fe.sub.91 Zr.sub.9 or (ii) Fe.sub.24 Zr.sub.76, the metallic glass being in ribbon form, and the synthesis being conducted at a temperature of 350.degree. to 420.degree. C.
Process for the production of an activated, vitreously-rigidified metallic glass consisting of (i) Fe and Zr or (ii) Fe, Zr and Mo, which is useful for the catalytic synthesis of ammonia from hydrogen and nitrogen, comprising:
