Mechanochemical promotion with molybdenum and catalytic activity of skeletal nickel catalysts in hydrogenation reactions

The possibility of mechanochemical promotion of skeletal nickel catalysts has been shown with the use of mechanical Ni−Al−Mo alloys as Raney nickel precursors in hydrogenation reactions. The mechanochemical promotion makes it possible to introduce molybdenum atoms into the catalyst lattice in the form of a solid solution. These catalysts are more active than pyrometallurgical ones. The increased activity of the catalysts in explained by changes in the structure and energetic state of the catalyst surface
