Abstract
This invention relates to the field of heterogeneous catalysis, and more particularly to catalysts including carbon supports having compositions which comprise one or more transition metals in combination with nitrogen and/or carbon formed on or over the surface of the carbon support. The present invention also relates to catalyst combinations comprising catalysts including carbon supports having compositions which comprise one or more transition metals in combination with nitrogen and/or carbon formed on or over the surface of a carbon support and a secondary catalyst or, co-catalyst, including a secondary transition metal. The invention further relates to the field of catalytic oxidation reactions, including the preparation of secondary amines by the catalytic oxidation of tertiary amines.
