The catalyst, contg. a polyvalent metal ions in a lower oxidn. state and used for chem. reactions such as for hydrogenation of org. compds., was produced bvy satn. of a solid oxide carrier contg. surface OH groups, such as silica gel, with the soln. of a polyvalent metal compd. contg. one or more alkenyl groups, type AnMXm (where M = a polyvalent metal, X = anion, A = alkenyl group, n ≠ 1, m ≠ 0), followed by heat treatment. To obtain the catalyst with a high concn. of polyvalent metal or poly- valent metal ions on the surface of a carrier, the heat treatment took place at 300-500° in the presence of H or H-contg.
