ABSTRACT:
Catalysts are described in which an active catalyst is disposed on a low surface area, oxide support. Methods of forming catalysts are described in which a Cr-containing metal is oxidized to form a chromium oxide layer and an active catalyst is applied directly on the chromium oxide layer. Methods of making new catalysts are described in which the surface is sonicated prior to depositing the catalyst. Catalyst systems and methods of oxidation are also described. The inventive systems, catalysts and methods are, in some instances, characterized by surprisingly superior results.
