Abstract
Provided herein are systems and methods for producing nano-particle-decorated catalytic surfaces by applying a current to conductive metal oxides. The nano-particle-decorated catalytic surfaces provide enhanced catalytic activity and are disclosed as anodes for oxidation reactions and cathodes for reduction reactions. Methods of electrocatalysis using the nano-particle decorated catalytic surfaces are also disclosed.
