Abstract
The present invention relates to a method for improving the catalytic activity of an oxygen evolution reaction (OER) catalyst comprising a substrate with a catalytic metallic composite coating. The method comprises exposing the metallic composite coating to a reducing agent to thereby increase oxygen vacancy density in the metallic composite coating.
Claims9
A method for improving the catalytic activity of an oxygen evolution reaction (OER) catalyst, the OER catalyst comprising a porous substrate with a porous catalytic metallic composite coating, the method comprising:
- exposing the porous metallic composite coating to a reducing agent in solution at a temperature of between 10° C. and 50° C., wherein the porous metallic composite coating is a nickel-iron composite;
- and
- reducing the nickel-iron composite upon the exposing of the porous metallic composite coating to the reducing agent so as to form a reduced nickel-iron composite having an increased oxygen vacancy density in the reduced nickel-iron composite as compared to the nickel-iron composite.
