Abstract
The present disclosure relates to a method to produce an oxygen evolution reaction electrode catalyst assembly comprising a dendritic nickel foam. The method is remarkable in that it comprises the steps of (a) providing a dendritic nickel foam material; (b) etching the dendritic nickel foam material by placing it in a etch solution being an acidic aqueous solution or an aqueous solution of metal chloride and recovering an etched dendritic nickel foam with nickel dendrites showing a chimney-like structure.
