Electrocatalyst production method and hydrogen production method

摘要

Provided is a method for producing an electrode catalyst that can produce an electrode including a sulfide containing a transition metal by a simple method and that can easily control the size of the obtained sulfide. The electrode manufacturing method of the present invention includes a first step of obtaining an oxide precursor by mixing a solvent containing an organic solvent, a compound containing Mo, and a compound containing a transition metal M other than Mo, and the precursor A second step of covering the body with an electrode substrate, and a third step of obtaining an electrode catalyst having a sulfide of the precursor by sulfiding the precursor coated on the electrode substrate.
