Abstract: The present invention relates to a Ni—Fe-based catalyst for OER doped with a metal having lower electronegativity than Ni and Fe, and a method for manufacturing the same. More specifically, the present invention offers the advantage of using nickel, a non-noble metal-based active catalyst, which has high economic value without the need for noble metals. The present invention provides a method for manufacturing a Ni—Fe-based catalyst for OER that exhibits excellent activity in oxygen generation reaction by maximizing the surface area compared to existing noble metal-based catalysts, thereby contributing significantly to the cost reduction of hydrogen production.
