Recent Applications of Amorphous Alloys to Design Skeletal Catalysts

Abstract: Amorphous alloys are still attracting great attention in the field of catalysis despite the fact that they have been investigated since the 1950s. One of the reasons why amorphous alloys have been in the spotlight until now, are their physical and chemical properties, which would make them suitable materials to be used as catalysts at industrial scale. This review deals with the recent research on applications of amorphous alloys for catalysis. These investigations were addressed to elucidate the relationship … Show more

“…Non-crystalline materials, such as amorphous metals, alloys, and glasses, are employed in a wide range of industrial processes and applications. , The atomic arrangement of disordered systems determines their physical, mechanical, chemical, and electrical properties. Several studies showed a strong correlation between the configurational local order and the electronic, , magnetic, catalytic, and corrosion-resistance properties of disordered systems, as found, for example, for the high-entropy alloys. , The structural order in amorphous solids is difficult to characterize, and it is far from being understood . Despite the lack of translational periodicity, amorphous systems are not completely random, being organized in hierarchical local structures at different length scales. The presence of microscopic-ordered arrangement, repetitive units, or defects is responsible for the macroscopic properties of the whole material.…”

“…Amorphous alloys are synthesized as metastable materials by rapid quenching of molten alloys, chemical reduction of metal precursor salts using borohydride (BH 4 – ) or hypophosphite (H 2 PO 2 – ), electrodeposition, , or ion-beam deposition . The rapid quenching method requires a high cooling rate (10 –5 –10 –6 K s –1 ) in an inert atmosphere or under high vacuum and typically results in very low specific surface area, which hampers its widespread and large-scale application.…”
