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.
本发明涉及异质催化领域,更特别地涉及包括碳载体的催化剂,其组成包括一个或多个过渡金属与氮和/或碳的组合物,形成在碳载体的表面上或上面。本发明还涉及催化剂组合物,包括包括碳载体的催化剂,其组成包括一个或多个过渡金属与氮和/或碳的组合物,形成在碳载体的表面上或上面,以及一个次要催化剂或共催化剂,包括一个次要过渡金属。本发明还涉及催化氧化反应领域,包括通过催化三级胺的氧化制备二级胺。
