CATALYSTS FOR HYDROGEN EVOLUTION REACTION INCLUDING TRANSITION METAL CHALCOGENIDE FILMS AND METHODS OF FORMING THE SAME

摘要

Catalysts for hydrogen evolution reaction (HER) and method of forming the catalysts are provided. The catalysts may include a metal chalcogenide film comprising chalcogen atom vacancies. A density of the chalcogen atom vacancies may be from about 5% to about 15%. The catalysts may further include a substrate on which the metal chalcogenide film extends. The substrate may include nickel, titanium, silver, zinc, and/or platinum. The catalysts may also include hydrogen ions disposed a surface of the metal chalcogenide film. The metal chalcogenide film may be a monolayer film including dopants, and the dopants may be nickel atoms, cobalt atoms, zinc atoms, iron atoms, rhenium (Re) atoms, and/or Niobium (Nb) atoms.
