摘要： The present invention provides a method for fabricating an electrode comprising a co-catalyst layer for splitting water with light. The method comprises steps of (a) forming a catalyst layer containing at least one selected from the group consisting of a niobium-containing oxynitride and a niobium-containing nitride on an electrically conductive principal surface of a substrate; (b) forming a transition metal oxide layer on the catalyst layer in an inert gas atmosphere containing oxidized gas impurities to provide a stacking structure comprising the substrate, the catalyst layer, and the transition metal oxide layer; (c) immersing the stacking structure in an electrolyte aqueous solution; and (d) applying a positive electric potential to the stacking structure in the electrolyte aqueous solution to convert the transition metal oxide layer into the co-catalyst layer. The present invention provides an electrode for water splitting having high water-splitting efficiency.
