  • Publication number: 20200056296
    Abstract: Disclosed is a method of manufacturing an electrocatalyst. The method may include forming a metal layer on a substrate, treating a substrate of the metal layer, and forming a catalyst layer on the metal layer by applying potential to an aqueous deposition solution including a nickel precursor, a copper precursor, a phosphorus precursor, and an additive, in which a molar ratio of the nickel precursor to the copper precursor may be greater than about 49:1. Accordingly, the present invention has an advantage in that the process of manufacturing the electrocatalyst may be simplified.
