Abstract
Novel nickel and/or cobalt plated sponge based catalysts are disclosed. The catalyst have an activity and/or selectivity comparable to conventional nickel and/or cobalt sponge catalysts, e.g., Raney® nickel or Raney® cobalt catalysts, but require a reduced content of nickel and/or cobalt. Catalysts in accordance with the invention comprise nickel and/or cobalt coated on at least a portion of the surface of a sponge support. Preferably, the sponge support comprises at least one metal other than or different from the metal(s) contained in the coating. The method of preparing the plated catalysts, and the method of using the catalysts in the preparation of organic compounds are also disclosed.
