【Abstract】 The development and applications of amorphous alloy catalyst are summarized. The most widely used techniques for the preparation of amorphous alloy catalyst are classified into rapid quenching method, chemical reduction method and impregnation-chemical reduction method. The reaction activity of the catalyst can be adjusted by changing the preparing condition, which including the calcination temperature, the metal load and the carrier. The amorphous structure, surface morphology and activity center can be determined and characterized by XRD, EXAFS, DSC, SEM, TEM and XPS. A detailed discussion of amorphous alloy catalyst in hydrogenation of unsaturated compound is presented.更多还原
