| Abstract: | Germanium, tin or lead additives decrease the activity of supported nickel by several orders of magnitude in the hydrogenation of benzene and hydrogenolysis of propane and n-hexane. n-Hexane is transformed to aromatization products, whereas non-modified Ni is known as a hydrogenolysis catalyst. These catalytic effects are due to changes in the electronic and chemisorption properties of nickel alloyed with inactive metals of the additives.
